Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184040, here are decompositions:
- 37 + 184003 = 184040
- 61 + 183979 = 184040
- 67 + 183973 = 184040
- 97 + 183943 = 184040
- 163 + 183877 = 184040
- 211 + 183829 = 184040
- 277 + 183763 = 184040
- 331 + 183709 = 184040
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 184,040 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 184040 first appears in π at position 17,755 of the decimal expansion (the 17,755ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
