Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158122, here are decompositions:
- 113 + 158009 = 158122
- 131 + 157991 = 158122
- 191 + 157931 = 158122
- 233 + 157889 = 158122
- 281 + 157841 = 158122
- 353 + 157769 = 158122
- 383 + 157739 = 158122
- 389 + 157733 = 158122
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 158,122 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
