Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121102, here are decompositions:
- 41 + 121061 = 121102
- 83 + 121019 = 121102
- 89 + 121013 = 121102
- 101 + 121001 = 121102
- 173 + 120929 = 121102
- 239 + 120863 = 121102
- 251 + 120851 = 121102
- 269 + 120833 = 121102
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 121,102 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
