Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105286, here are decompositions:

17 + 105269 = 105286
23 + 105263 = 105286
47 + 105239 = 105286
59 + 105227 = 105286
113 + 105173 = 105286
149 + 105137 = 105286
179 + 105107 = 105286
263 + 105023 = 105286

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 105.286 and was likely granted around 1870.

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