Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190178, here are decompositions:

19 + 190159 = 190178
31 + 190147 = 190178
127 + 190051 = 190178
151 + 190027 = 190178
181 + 189997 = 190178
211 + 189967 = 190178
229 + 189949 = 190178
277 + 189901 = 190178

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 190,178 and was likely granted around 1875.

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