Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100318, here are decompositions:
- 5 + 100313 = 100318
- 47 + 100271 = 100318
- 149 + 100169 = 100318
- 167 + 100151 = 100318
- 269 + 100049 = 100318
- 347 + 99971 = 100318
- 389 + 99929 = 100318
- 479 + 99839 = 100318
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 100,318 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
