Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022144, here are decompositions:

3 + 1022141 = 1022144
7 + 1022137 = 1022144
31 + 1022113 = 1022144
61 + 1022083 = 1022144
73 + 1022071 = 1022144
127 + 1022017 = 1022144
181 + 1021963 = 1022144
283 + 1021861 = 1022144

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 1,022,144 and was likely granted around 1912.

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