Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126340, here are decompositions:
- 3 + 126337 = 126340
- 17 + 126323 = 126340
- 23 + 126317 = 126340
- 29 + 126311 = 126340
- 83 + 126257 = 126340
- 107 + 126233 = 126340
- 113 + 126227 = 126340
- 167 + 126173 = 126340
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 126,340 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
