Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040020, here are decompositions:

41 + 1039979 = 1040020
71 + 1039949 = 1040020
89 + 1039931 = 1040020
197 + 1039823 = 1040020
251 + 1039769 = 1040020
257 + 1039763 = 1040020
353 + 1039667 = 1040020
389 + 1039631 = 1040020

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 1,040,020 and was likely granted around 1912.

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