Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180512, here are decompositions:

151 + 180361 = 180512
181 + 180331 = 180512
223 + 180289 = 180512
271 + 180241 = 180512
331 + 180181 = 180512
439 + 180073 = 180512
523 + 179989 = 180512
613 + 179899 = 180512

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 180,512 and was likely granted around 1875.

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