Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100808, here are decompositions:
- 7 + 100801 = 100808
- 61 + 100747 = 100808
- 67 + 100741 = 100808
- 109 + 100699 = 100808
- 139 + 100669 = 100808
- 199 + 100609 = 100808
- 271 + 100537 = 100808
- 307 + 100501 = 100808
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 100,808 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
