Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121204, here are decompositions:
- 23 + 121181 = 121204
- 47 + 121157 = 121204
- 53 + 121151 = 121204
- 137 + 121067 = 121204
- 191 + 121013 = 121204
- 197 + 121007 = 121204
- 227 + 120977 = 121204
- 257 + 120947 = 121204
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 121,204 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
