Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100286, here are decompositions:

7 + 100279 = 100286
19 + 100267 = 100286
73 + 100213 = 100286
79 + 100207 = 100286
97 + 100189 = 100286
103 + 100183 = 100286
157 + 100129 = 100286
229 + 100057 = 100286

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,286 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
