Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184240, here are decompositions:
- 29 + 184211 = 184240
- 41 + 184199 = 184240
- 53 + 184187 = 184240
- 59 + 184181 = 184240
- 83 + 184157 = 184240
- 107 + 184133 = 184240
- 167 + 184073 = 184240
- 197 + 184043 = 184240
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 184,240 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 184240 first appears in π at position 471,285 of the decimal expansion (the 471,285ordinal-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.
