Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180150, here are decompositions:

13 + 180137 = 180150
53 + 180097 = 180150
73 + 180077 = 180150
79 + 180071 = 180150
97 + 180053 = 180150
107 + 180043 = 180150
127 + 180023 = 180150
149 + 180001 = 180150

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 180,150 and was likely granted around 1875.

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