Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180168, here are decompositions:

7 + 180161 = 180168
31 + 180137 = 180168
71 + 180097 = 180168
97 + 180071 = 180168
167 + 180001 = 180168
179 + 179989 = 180168
199 + 179969 = 180168
211 + 179957 = 180168

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 180,168 and was likely granted around 1875.

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