Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122630, here are decompositions:
- 19 + 122611 = 122630
- 31 + 122599 = 122630
- 73 + 122557 = 122630
- 97 + 122533 = 122630
- 103 + 122527 = 122630
- 127 + 122503 = 122630
- 181 + 122449 = 122630
- 229 + 122401 = 122630
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 122,630 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
