Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190500, here are decompositions:

29 + 190471 = 190500
97 + 190403 = 190500
109 + 190391 = 190500
113 + 190387 = 190500
131 + 190369 = 190500
179 + 190321 = 190500
199 + 190301 = 190500
229 + 190271 = 190500

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 190,500 and was likely granted around 1875.

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