Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122288, here are decompositions:
- 37 + 122251 = 122288
- 79 + 122209 = 122288
- 139 + 122149 = 122288
- 157 + 122131 = 122288
- 277 + 122011 = 122288
- 337 + 121951 = 122288
- 367 + 121921 = 122288
- 379 + 121909 = 122288
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 122,288 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
