Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125164, here are decompositions:
- 23 + 125141 = 125164
- 47 + 125117 = 125164
- 71 + 125093 = 125164
- 101 + 125063 = 125164
- 173 + 124991 = 125164
- 257 + 124907 = 125164
- 311 + 124853 = 125164
- 317 + 124847 = 125164
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 125,164 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 125164 first appears in π at position 974,236 of the decimal expansion (the 974,236ordinal-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.
