Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022100, here are decompositions:

17 + 1022083 = 1022100
29 + 1022071 = 1022100
41 + 1022059 = 1022100
47 + 1022053 = 1022100
67 + 1022033 = 1022100
83 + 1022017 = 1022100
89 + 1022011 = 1022100
127 + 1021973 = 1022100

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 1,022,100 and was likely granted around 1912.

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