Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122164, here are decompositions:
- 17 + 122147 = 122164
- 47 + 122117 = 122164
- 83 + 122081 = 122164
- 113 + 122051 = 122164
- 131 + 122033 = 122164
- 137 + 122027 = 122164
- 167 + 121997 = 122164
- 197 + 121967 = 122164
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 122,164 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
