Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187624, here are decompositions:
- 191 + 187433 = 187624
- 251 + 187373 = 187624
- 257 + 187367 = 187624
- 263 + 187361 = 187624
- 347 + 187277 = 187624
- 401 + 187223 = 187624
- 431 + 187193 = 187624
- 443 + 187181 = 187624
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 187,624 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 187624 first appears in π at position 378,254 of the decimal expansion (the 378,254ordinal-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.
