Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022864, here are decompositions:

43 + 1022821 = 1022864
67 + 1022797 = 1022864
103 + 1022761 = 1022864
163 + 1022701 = 1022864
181 + 1022683 = 1022864
211 + 1022653 = 1022864
373 + 1022491 = 1022864
397 + 1022467 = 1022864

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 1,022,864 and was likely granted around 1912.

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