Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015020, here are decompositions:

11 + 1015009 = 1015020
31 + 1014989 = 1015020
47 + 1014973 = 1015020
67 + 1014953 = 1015020
79 + 1014941 = 1015020
113 + 1014907 = 1015020
131 + 1014889 = 1015020
151 + 1014869 = 1015020

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 1,015,020 and was likely granted around 1911.

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