Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023040, here are decompositions:

3 + 1023037 = 1023040
59 + 1022981 = 1023040
107 + 1022933 = 1023040
149 + 1022891 = 1023040
191 + 1022849 = 1023040
197 + 1022843 = 1023040
311 + 1022729 = 1023040
401 + 1022639 = 1023040

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 1,023,040 and was likely granted around 1912.

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