Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180196, here are decompositions:

17 + 180179 = 180196
59 + 180137 = 180196
173 + 180023 = 180196
197 + 179999 = 180196
227 + 179969 = 180196
239 + 179957 = 180196
257 + 179939 = 180196
293 + 179903 = 180196

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 180,196 and was likely granted around 1875.

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