Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100718, here are decompositions:
- 19 + 100699 = 100718
- 97 + 100621 = 100718
- 109 + 100609 = 100718
- 127 + 100591 = 100718
- 181 + 100537 = 100718
- 199 + 100519 = 100718
- 271 + 100447 = 100718
- 307 + 100411 = 100718
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 100,718 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
