Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180016, here are decompositions:

17 + 179999 = 180016
47 + 179969 = 180016
59 + 179957 = 180016
107 + 179909 = 180016
113 + 179903 = 180016
167 + 179849 = 180016
197 + 179819 = 180016
359 + 179657 = 180016

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 180,016 and was likely granted around 1875.

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