Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100680, here are decompositions:
- 7 + 100673 = 100680
- 11 + 100669 = 100680
- 31 + 100649 = 100680
- 59 + 100621 = 100680
- 67 + 100613 = 100680
- 71 + 100609 = 100680
- 89 + 100591 = 100680
- 131 + 100549 = 100680
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 100,680 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
