Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180368, here are decompositions:

7 + 180361 = 180368
31 + 180337 = 180368
37 + 180331 = 180368
61 + 180307 = 180368
79 + 180289 = 180368
109 + 180259 = 180368
127 + 180241 = 180368
157 + 180211 = 180368

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 180,368 and was likely granted around 1875.

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