Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190220, here are decompositions:

13 + 190207 = 190220
61 + 190159 = 190220
73 + 190147 = 190220
127 + 190093 = 190220
157 + 190063 = 190220
193 + 190027 = 190220
223 + 189997 = 190220
271 + 189949 = 190220

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 190,220 and was likely granted around 1875.

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