Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188360, here are decompositions:

37 + 188323 = 188360
43 + 188317 = 188360
61 + 188299 = 188360
79 + 188281 = 188360
163 + 188197 = 188360
181 + 188179 = 188360
223 + 188137 = 188360
331 + 188029 = 188360

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 188,360 and was likely granted around 1875.

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