Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100788, here are decompositions:
- 19 + 100769 = 100788
- 41 + 100747 = 100788
- 47 + 100741 = 100788
- 89 + 100699 = 100788
- 139 + 100649 = 100788
- 167 + 100621 = 100788
- 179 + 100609 = 100788
- 197 + 100591 = 100788
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 100,788 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
