Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101810, here are decompositions:

3 + 101807 = 101810
13 + 101797 = 101810
61 + 101749 = 101810
73 + 101737 = 101810
109 + 101701 = 101810
157 + 101653 = 101810
199 + 101611 = 101810
211 + 101599 = 101810

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 101,810 and was likely granted around 1870.

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