Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125664, here are decompositions:
- 5 + 125659 = 125664
- 13 + 125651 = 125664
- 23 + 125641 = 125664
- 37 + 125627 = 125664
- 43 + 125621 = 125664
- 47 + 125617 = 125664
- 67 + 125597 = 125664
- 73 + 125591 = 125664
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 125,664 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 125664 first appears in π at position 162,765 of the decimal expansion (the 162,765ordinal-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.
