Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100000, here are decompositions:
- 11 + 99989 = 100000
- 29 + 99971 = 100000
- 71 + 99929 = 100000
- 167 + 99833 = 100000
- 191 + 99809 = 100000
- 233 + 99767 = 100000
- 239 + 99761 = 100000
- 281 + 99719 = 100000
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 100,000 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
