Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185066, here are decompositions:

3 + 185063 = 185066
67 + 184999 = 185066
73 + 184993 = 185066
97 + 184969 = 185066
109 + 184957 = 185066
163 + 184903 = 185066
223 + 184843 = 185066
229 + 184837 = 185066

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 185,066 and was likely granted around 1875.

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