Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180328, here are decompositions:

11 + 180317 = 180328
17 + 180311 = 180328
41 + 180287 = 180328
47 + 180281 = 180328
89 + 180239 = 180328
107 + 180221 = 180328
149 + 180179 = 180328
167 + 180161 = 180328

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 180,328 and was likely granted around 1875.

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