Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142862, here are decompositions:
- 73 + 142789 = 142862
- 103 + 142759 = 142862
- 151 + 142711 = 142862
- 163 + 142699 = 142862
- 271 + 142591 = 142862
- 409 + 142453 = 142862
- 631 + 142231 = 142862
- 673 + 142189 = 142862
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 142,862 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
