Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187426, here are decompositions:
- 3 + 187423 = 187426
- 17 + 187409 = 187426
- 47 + 187379 = 187426
- 53 + 187373 = 187426
- 59 + 187367 = 187426
- 89 + 187337 = 187426
- 149 + 187277 = 187426
- 233 + 187193 = 187426
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 187,426 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 187426 first appears in π at position 512,009 of the decimal expansion (the 512,009ordinal-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.
