Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126312, here are decompositions:
- 5 + 126307 = 126312
- 41 + 126271 = 126312
- 71 + 126241 = 126312
- 79 + 126233 = 126312
- 83 + 126229 = 126312
- 89 + 126223 = 126312
- 101 + 126211 = 126312
- 113 + 126199 = 126312
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 126,312 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
