Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188086, here are decompositions:

113 + 187973 = 188086
179 + 187907 = 188086
263 + 187823 = 188086
293 + 187793 = 188086
449 + 187637 = 188086
617 + 187469 = 188086
653 + 187433 = 188086
677 + 187409 = 188086

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 188,086 and was likely granted around 1875.

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