Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184742, here are decompositions:
- 31 + 184711 = 184742
- 73 + 184669 = 184742
- 109 + 184633 = 184742
- 373 + 184369 = 184742
- 409 + 184333 = 184742
- 421 + 184321 = 184742
- 433 + 184309 = 184742
- 463 + 184279 = 184742
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 184,742 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 184742 first appears in π at position 41,407 of the decimal expansion (the 41,407ordinal-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.
