Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025040, here are decompositions:

11 + 1025029 = 1025040
19 + 1025021 = 1025040
31 + 1025009 = 1025040
43 + 1024997 = 1025040
53 + 1024987 = 1025040
83 + 1024957 = 1025040
89 + 1024951 = 1025040
97 + 1024943 = 1025040

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 1,025,040 and was likely granted around 1912.

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