Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022870, here are decompositions:

73 + 1022797 = 1022870
97 + 1022773 = 1022870
109 + 1022761 = 1022870
151 + 1022719 = 1022870
181 + 1022689 = 1022870
193 + 1022677 = 1022870
241 + 1022629 = 1022870
367 + 1022503 = 1022870

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 1,022,870 and was likely granted around 1912.

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