Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187124, here are decompositions:
- 13 + 187111 = 187124
- 43 + 187081 = 187124
- 97 + 187027 = 187124
- 241 + 186883 = 187124
- 283 + 186841 = 187124
- 331 + 186793 = 187124
- 367 + 186757 = 187124
- 397 + 186727 = 187124
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 187,124 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 187124 first appears in π at position 60,308 of the decimal expansion (the 60,308ordinal-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.
