Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100656, here are decompositions:
- 7 + 100649 = 100656
- 43 + 100613 = 100656
- 47 + 100609 = 100656
- 97 + 100559 = 100656
- 107 + 100549 = 100656
- 109 + 100547 = 100656
- 137 + 100519 = 100656
- 139 + 100517 = 100656
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 100,656 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
