Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185146, here are decompositions:

23 + 185123 = 185146
47 + 185099 = 185146
83 + 185063 = 185146
89 + 185057 = 185146
149 + 184997 = 185146
179 + 184967 = 185146
197 + 184949 = 185146
233 + 184913 = 185146

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 185,146 and was likely granted around 1875.

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