Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101020, here are decompositions:

11 + 101009 = 101020
83 + 100937 = 101020
89 + 100931 = 101020
107 + 100913 = 101020
113 + 100907 = 101020
167 + 100853 = 101020
173 + 100847 = 101020
191 + 100829 = 101020

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 101,020 and was likely granted around 1870.

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