Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126904, here are decompositions:
- 47 + 126857 = 126904
- 53 + 126851 = 126904
- 191 + 126713 = 126904
- 251 + 126653 = 126904
- 263 + 126641 = 126904
- 293 + 126611 = 126904
- 353 + 126551 = 126904
- 431 + 126473 = 126904
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 126,904 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 126904 first appears in π at position 513,466 of the decimal expansion (the 513,466ordinal-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.
