Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190000, here are decompositions:

3 + 189997 = 190000
11 + 189989 = 190000
17 + 189983 = 190000
23 + 189977 = 190000
53 + 189947 = 190000
71 + 189929 = 190000
113 + 189887 = 190000
149 + 189851 = 190000

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 190,000 and was likely granted around 1875.

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