Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023020, here are decompositions:

43 + 1022977 = 1023020
109 + 1022911 = 1023020
139 + 1022881 = 1023020
151 + 1022869 = 1023020
199 + 1022821 = 1023020
223 + 1022797 = 1023020
331 + 1022689 = 1023020
337 + 1022683 = 1023020

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 1,023,020 and was likely granted around 1912.

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