Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125404, here are decompositions:
- 5 + 125399 = 125404
- 17 + 125387 = 125404
- 101 + 125303 = 125404
- 173 + 125231 = 125404
- 197 + 125207 = 125404
- 263 + 125141 = 125404
- 311 + 125093 = 125404
- 401 + 125003 = 125404
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 125,404 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 125404 first appears in π at position 606,753 of the decimal expansion (the 606,753ordinal-suffix:rd 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.
