Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510816, here are decompositions:

13 + 510803 = 510816
23 + 510793 = 510816
43 + 510773 = 510816
107 + 510709 = 510816
109 + 510707 = 510816
139 + 510677 = 510816
197 + 510619 = 510816
199 + 510617 = 510816

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 510,816 and was likely granted around 1893.

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