Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021976, here are decompositions:

3 + 1021973 = 1021976
13 + 1021963 = 1021976
79 + 1021897 = 1021976
97 + 1021879 = 1021976
127 + 1021849 = 1021976
139 + 1021837 = 1021976
199 + 1021777 = 1021976
223 + 1021753 = 1021976

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 1,021,976 and was likely granted around 1912.

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