Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187704, here are decompositions:
- 5 + 187699 = 187704
- 17 + 187687 = 187704
- 43 + 187661 = 187704
- 53 + 187651 = 187704
- 67 + 187637 = 187704
- 71 + 187633 = 187704
- 73 + 187631 = 187704
- 107 + 187597 = 187704
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 187,704 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 187704 first appears in π at position 688,009 of the decimal expansion (the 688,009ordinal-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.
