Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500800, here are decompositions:

23 + 500777 = 500800
59 + 500741 = 500800
71 + 500729 = 500800
101 + 500699 = 500800
107 + 500693 = 500800
197 + 500603 = 500800
233 + 500567 = 500800
281 + 500519 = 500800

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 500,800 and was likely granted around 1893.

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