Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142922, here are decompositions:
- 19 + 142903 = 142922
- 151 + 142771 = 142922
- 163 + 142759 = 142922
- 211 + 142711 = 142922
- 223 + 142699 = 142922
- 313 + 142609 = 142922
- 331 + 142591 = 142922
- 349 + 142573 = 142922
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 142,922 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
