Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180286, here are decompositions:

5 + 180281 = 180286
23 + 180263 = 180286
47 + 180239 = 180286
53 + 180233 = 180286
107 + 180179 = 180286
149 + 180137 = 180286
233 + 180053 = 180286
263 + 180023 = 180286

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 180,286 and was likely granted around 1875.

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