Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122146, here are decompositions:
- 29 + 122117 = 122146
- 47 + 122099 = 122146
- 107 + 122039 = 122146
- 113 + 122033 = 122146
- 149 + 121997 = 122146
- 179 + 121967 = 122146
- 197 + 121949 = 122146
- 257 + 121889 = 122146
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 122,146 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
