Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185158, here are decompositions:

5 + 185153 = 185158
59 + 185099 = 185158
89 + 185069 = 185158
101 + 185057 = 185158
107 + 185051 = 185158
131 + 185027 = 185158
137 + 185021 = 185158
191 + 184967 = 185158

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 185,158 and was likely granted around 1875.

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