Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122636, here are decompositions:
- 37 + 122599 = 122636
- 79 + 122557 = 122636
- 103 + 122533 = 122636
- 109 + 122527 = 122636
- 127 + 122509 = 122636
- 139 + 122497 = 122636
- 193 + 122443 = 122636
- 313 + 122323 = 122636
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 122,636 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
