Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126142, here are decompositions:
- 11 + 126131 = 126142
- 101 + 126041 = 126142
- 131 + 126011 = 126142
- 179 + 125963 = 126142
- 353 + 125789 = 126142
- 389 + 125753 = 126142
- 431 + 125711 = 126142
- 449 + 125693 = 126142
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 126,142 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
