Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125406, here are decompositions:
- 7 + 125399 = 125406
- 19 + 125387 = 125406
- 23 + 125383 = 125406
- 53 + 125353 = 125406
- 67 + 125339 = 125406
- 103 + 125303 = 125406
- 107 + 125299 = 125406
- 137 + 125269 = 125406
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 125,406 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 125406 first appears in π at position 916,352 of the decimal expansion (the 916,352ordinal-suffix:nd 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.
