Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142460, here are decompositions:
- 7 + 142453 = 142460
- 79 + 142381 = 142460
- 103 + 142357 = 142460
- 163 + 142297 = 142460
- 223 + 142237 = 142460
- 229 + 142231 = 142460
- 271 + 142189 = 142460
- 277 + 142183 = 142460
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 142,460 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
