Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180066, here are decompositions:

13 + 180053 = 180066
23 + 180043 = 180066
43 + 180023 = 180066
59 + 180007 = 180066
67 + 179999 = 180066
97 + 179969 = 180066
109 + 179957 = 180066
113 + 179953 = 180066

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 180,066 and was likely granted around 1875.

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