Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100810, here are decompositions:

11 + 100799 = 100810
23 + 100787 = 100810
41 + 100769 = 100810
107 + 100703 = 100810
137 + 100673 = 100810
197 + 100613 = 100810
251 + 100559 = 100810
263 + 100547 = 100810

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 100,810 and was likely granted around 1870.

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