Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001810, here are decompositions:

3 + 1001807 = 1001810
13 + 1001797 = 1001810
67 + 1001743 = 1001810
97 + 1001713 = 1001810
127 + 1001683 = 1001810
151 + 1001659 = 1001810
181 + 1001629 = 1001810
223 + 1001587 = 1001810

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 1,001,810 and was likely granted around 1911.

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