Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126404, here are decompositions:
- 7 + 126397 = 126404
- 67 + 126337 = 126404
- 97 + 126307 = 126404
- 163 + 126241 = 126404
- 181 + 126223 = 126404
- 193 + 126211 = 126404
- 277 + 126127 = 126404
- 307 + 126097 = 126404
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 126,404 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 126404 first appears in π at position 958,585 of the decimal expansion (the 958,585ordinal-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.
