Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519020, here are decompositions:

31 + 518989 = 519020
37 + 518983 = 519020
67 + 518953 = 519020
109 + 518911 = 519020
127 + 518893 = 519020
157 + 518863 = 519020
211 + 518809 = 519020
241 + 518779 = 519020

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 519,020 and was likely granted around 1894.

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