Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121004, here are decompositions:
- 3 + 121001 = 121004
- 7 + 120997 = 121004
- 61 + 120943 = 121004
- 67 + 120937 = 121004
- 97 + 120907 = 121004
- 127 + 120877 = 121004
- 157 + 120847 = 121004
- 181 + 120823 = 121004
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 121,004 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
