Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190020, here are decompositions:

23 + 189997 = 190020
31 + 189989 = 190020
37 + 189983 = 190020
43 + 189977 = 190020
53 + 189967 = 190020
59 + 189961 = 190020
71 + 189949 = 190020
73 + 189947 = 190020

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 190,020 and was likely granted around 1875.

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