Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042040, here are decompositions:

19 + 1042021 = 1042040
79 + 1041961 = 1042040
151 + 1041889 = 1042040
199 + 1041841 = 1042040
211 + 1041829 = 1042040
283 + 1041757 = 1042040
367 + 1041673 = 1042040
397 + 1041643 = 1042040

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 1,042,040 and was likely granted around 1912.

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