Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188918, here are decompositions:

7 + 188911 = 188918
61 + 188857 = 188918
127 + 188791 = 188918
139 + 188779 = 188918
151 + 188767 = 188918
199 + 188719 = 188918
211 + 188707 = 188918
241 + 188677 = 188918

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 188,918 and was likely granted around 1875.

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