Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120668, here are decompositions:
- 7 + 120661 = 120668
- 61 + 120607 = 120668
- 157 + 120511 = 120668
- 241 + 120427 = 120668
- 271 + 120397 = 120668
- 277 + 120391 = 120668
- 337 + 120331 = 120668
- 349 + 120319 = 120668
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 120,668 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
