Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122162, here are decompositions:
- 13 + 122149 = 122162
- 31 + 122131 = 122162
- 109 + 122053 = 122162
- 151 + 122011 = 122162
- 199 + 121963 = 122162
- 211 + 121951 = 122162
- 241 + 121921 = 122162
- 373 + 121789 = 122162
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 122,162 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
