Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133180, here are decompositions:

11 + 133169 = 133180
23 + 133157 = 133180
59 + 133121 = 133180
71 + 133109 = 133180
83 + 133097 = 133180
107 + 133073 = 133180
167 + 133013 = 133180
191 + 132989 = 133180

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 133,180 and was likely granted around 1872.

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