Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190450, here are decompositions:

41 + 190409 = 190450
47 + 190403 = 190450
59 + 190391 = 190450
83 + 190367 = 190450
137 + 190313 = 190450
149 + 190301 = 190450
167 + 190283 = 190450
179 + 190271 = 190450

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 190,450 and was likely granted around 1875.

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