Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187010, here are decompositions:

7 + 187003 = 187010
127 + 186883 = 187010
139 + 186871 = 187010
151 + 186859 = 187010
211 + 186799 = 187010
277 + 186733 = 187010
283 + 186727 = 187010
331 + 186679 = 187010

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 187,010 and was likely granted around 1875.

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