Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188018, here are decompositions:

7 + 188011 = 188018
31 + 187987 = 188018
67 + 187951 = 188018
97 + 187921 = 188018
109 + 187909 = 188018
157 + 187861 = 188018
307 + 187711 = 188018
331 + 187687 = 188018

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 188,018 and was likely granted around 1875.

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