Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180366, here are decompositions:

5 + 180361 = 180366
19 + 180347 = 180366
29 + 180337 = 180366
59 + 180307 = 180366
79 + 180287 = 180366
103 + 180263 = 180366
107 + 180259 = 180366
127 + 180239 = 180366

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 180,366 and was likely granted around 1875.

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