Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184440, here are decompositions:
- 23 + 184417 = 184440
- 31 + 184409 = 184440
- 71 + 184369 = 184440
- 89 + 184351 = 184440
- 103 + 184337 = 184440
- 107 + 184333 = 184440
- 131 + 184309 = 184440
- 149 + 184291 = 184440
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 184,440 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 184440 first appears in π at position 652,917 of the decimal expansion (the 652,917ordinal-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.
