Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513800, here are decompositions:

19 + 513781 = 513800
31 + 513769 = 513800
61 + 513739 = 513800
73 + 513727 = 513800
103 + 513697 = 513800
109 + 513691 = 513800
127 + 513673 = 513800
151 + 513649 = 513800

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 513,800 and was likely granted around 1893.

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