Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121304, here are decompositions:
- 13 + 121291 = 121304
- 37 + 121267 = 121304
- 181 + 121123 = 121304
- 223 + 121081 = 121304
- 241 + 121063 = 121304
- 283 + 121021 = 121304
- 307 + 120997 = 121304
- 367 + 120937 = 121304
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 121,304 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
