Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162100, here are decompositions:

41 + 162059 = 162100
47 + 162053 = 162100
83 + 162017 = 162100
89 + 162011 = 162100
101 + 161999 = 162100
131 + 161969 = 162100
179 + 161921 = 162100
227 + 161873 = 162100

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 162,100 and was likely granted around 1874.

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