Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180288, here are decompositions:

7 + 180281 = 180288
29 + 180259 = 180288
41 + 180247 = 180288
47 + 180241 = 180288
67 + 180221 = 180288
107 + 180181 = 180288
109 + 180179 = 180288
127 + 180161 = 180288

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 180,288 and was likely granted around 1875.

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