Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108680, here are decompositions:
- 3 + 108677 = 108680
- 31 + 108649 = 108680
- 37 + 108643 = 108680
- 43 + 108637 = 108680
- 109 + 108571 = 108680
- 127 + 108553 = 108680
- 139 + 108541 = 108680
- 151 + 108529 = 108680
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 108,680 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
