Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126342, here are decompositions:
- 5 + 126337 = 126342
- 19 + 126323 = 126342
- 31 + 126311 = 126342
- 71 + 126271 = 126342
- 101 + 126241 = 126342
- 109 + 126233 = 126342
- 113 + 126229 = 126342
- 131 + 126211 = 126342
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 126,342 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
