Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100386, here are decompositions:
- 7 + 100379 = 100386
- 23 + 100363 = 100386
- 29 + 100357 = 100386
- 43 + 100343 = 100386
- 53 + 100333 = 100386
- 73 + 100313 = 100386
- 89 + 100297 = 100386
- 107 + 100279 = 100386
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 100,386 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
