Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190170, here are decompositions:

11 + 190159 = 190170
23 + 190147 = 190170
41 + 190129 = 190170
73 + 190097 = 190170
107 + 190063 = 190170
139 + 190031 = 190170
173 + 189997 = 190170
181 + 189989 = 190170

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 190,170 and was likely granted around 1875.

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