Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027800, here are decompositions:

13 + 1027787 = 1027800
17 + 1027783 = 1027800
23 + 1027777 = 1027800
41 + 1027759 = 1027800
43 + 1027757 = 1027800
47 + 1027753 = 1027800
61 + 1027739 = 1027800
73 + 1027727 = 1027800

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 1,027,800 and was likely granted around 1912.

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