Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180458, here are decompositions:

67 + 180391 = 180458
79 + 180379 = 180458
97 + 180361 = 180458
127 + 180331 = 180458
151 + 180307 = 180458
199 + 180259 = 180458
211 + 180247 = 180458
277 + 180181 = 180458

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 180,458 and was likely granted around 1875.

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