Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105250, here are decompositions:

11 + 105239 = 105250
23 + 105227 = 105250
83 + 105167 = 105250
107 + 105143 = 105250
113 + 105137 = 105250
179 + 105071 = 105250
227 + 105023 = 105250
251 + 104999 = 105250

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 105,250 and was likely granted around 1870.

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