In short
Your name in Hebrew letters is דקלן. Adding up the numbers of its letters gives 184 — the same as the Torah word פקד, “to visit, number”. That number points to Torah page 184 of 354 — in the portion Shmini. What that portion is about: The eighth day: Aaron's first service; fire from heaven; the death of Nadab and Abihu; clean and unclean animals. The verse that begins with the first letter of your name and ends with the last is Leviticus 23:10. Each of these steps is laid out below with its sources. Every figure can be checked by hand.

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) — 834. A Torah word with the same number is משפחתו — “his family” (Leviticus 25:10).
Reduced, each letter to one digit (mispar katan) — 13. A Torah word with the same number is אחד — “one” (Genesis 1:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 49. A Torah word with the same number is מואב — “Moab, son of Lot” (Genesis 19:37).
Cumulative: a letter plus all letters before it (mispar kidmi) — 905.
Squares of the letter values (mispar perati) — 13416.
Building: the sum grows with each letter (mispar bone’eh) — 426. A Torah word with the same number is תוך — “midst, middle” (Genesis 1:6).
The letters that come out are קדכט — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 133.
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 800. A Torah word with the same number is קשת — “bow” (Genesis 9:13).
The number 184 appears in the classical books 8 times across 7 works. The earliest mention is ספר קרניים (~1400).

The name דקלן does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
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 דקלן these are ד and נ. The Pentateuch has 3 such verses. The first of them is Leviticus 23:10:
דבר אל בני ישראל ואמרת אלהם כי תבאו אל הארץ אשר אני נתן לכם וקצרתם את קצירה והבאתם את עמר ראשית קצירכם אל הכהן
This is from the portion Emor. What it is about: Laws of the priests; animals without blemish; the calendar of festivals — from the Sabbath to Sukkot; the lamp and the showbread.
