Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180338, here are decompositions:

7 + 180331 = 180338
31 + 180307 = 180338
79 + 180259 = 180338
97 + 180241 = 180338
127 + 180211 = 180338
157 + 180181 = 180338
241 + 180097 = 180338
331 + 180007 = 180338

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 180,338 and was likely granted around 1875.

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