Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122804, here are decompositions:
- 43 + 122761 = 122804
- 61 + 122743 = 122804
- 103 + 122701 = 122804
- 151 + 122653 = 122804
- 193 + 122611 = 122804
- 271 + 122533 = 122804
- 277 + 122527 = 122804
- 307 + 122497 = 122804
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 122,804 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
