Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125804, here are decompositions:
- 13 + 125791 = 125804
- 61 + 125743 = 125804
- 67 + 125737 = 125804
- 73 + 125731 = 125804
- 97 + 125707 = 125804
- 163 + 125641 = 125804
- 277 + 125527 = 125804
- 307 + 125497 = 125804
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 125,804 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 125804 first appears in π at position 556,656 of the decimal expansion (the 556,656ordinal-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.
