Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500820, here are decompositions:

11 + 500809 = 500820
13 + 500807 = 500820
29 + 500791 = 500820
43 + 500777 = 500820
79 + 500741 = 500820
97 + 500723 = 500820
101 + 500719 = 500820
107 + 500713 = 500820

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 500,820 and was likely granted around 1893.

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