The name Gideoni in Hebrew letters is גדעני. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
גדעני
In short
Your name in Hebrew letters is גדעני. A Tanakh name: an Israelite (first in Numbers 1:11; 5 mentions in the Tanakh). Adding up the numbers of its letters gives 137 — the same as the Torah word מצבה, “pillar”. That number points to Torah page 137 of 354 — in the portion Terumah. What that portion is about: The offering for the Sanctuary; the Ark, the table and the lampstand; the Tabernacle and its curtains; the altar. The verse that begins with the first letter of your name and ends with the last is Genesis 23:4. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Gideoni” — this exact spelling is what was calculated: גדעני. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name גדעני gives 137.
137
The number 137 is the Torah word מצבה — «pillar» (Genesis 28:18).
And thou shalt make a screen for the door of the Tent, of blue, and purple, and scarlet, and fine twined linen, the work of the weaver in colours.
This is from the portion Terumah. What it is about: The offering for the Sanctuary; the Ark, the table and the lampstand; the Tabernacle and its curtains; the altar.
Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 137. A Torah word with the same number is מצבה — “pillar” (Genesis 28:18).
Reduced, each letter to one digit (mispar katan) — 20. A Torah word with the same number is היה — “to be, become” (Genesis 1:2).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 47. A Torah word with the same number is אולי — “perhaps” (Genesis 16:2).
Cumulative: a letter plus all letters before it (mispar kidmi) — 591. A Torah word with the same number is תקופה — “turn of the year” (Exodus 34:22).
Squares of the letter values (mispar perati) — 7525.
Building: the sum grows with each letter (mispar bone’eh) — 351. A Torah word with the same number is נשא — “to lift, carry” (Genesis 4:13).
The letters that come out are רקזטמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 356. A Torah word with the same number is פעור — “Peor, mountain in Moab” (Numbers 23:28).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 773.
The number 137 appears in the classical books 8 times across 6 works. The earliest mention is עץ חיים (~1573).

The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For גדעני these are ג and י. The Pentateuch has 2 such verses. The first of them is Genesis 23:4:
This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
