Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188080, here are decompositions:

59 + 188021 = 188080
107 + 187973 = 188080
149 + 187931 = 188080
173 + 187907 = 188080
197 + 187883 = 188080
257 + 187823 = 188080
293 + 187787 = 188080
317 + 187763 = 188080

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 188,080 and was likely granted around 1875.

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