Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163100, here are decompositions:

37 + 163063 = 163100
73 + 163027 = 163100
79 + 163021 = 163100
97 + 163003 = 163100
103 + 162997 = 163100
127 + 162973 = 163100
163 + 162937 = 163100
193 + 162907 = 163100

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 163,100 and was likely granted around 1874.

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