Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516020, here are decompositions:

3 + 516017 = 516020
79 + 515941 = 516020
97 + 515923 = 516020
103 + 515917 = 516020
163 + 515857 = 516020
181 + 515839 = 516020
283 + 515737 = 516020
367 + 515653 = 516020

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 516,020 and was likely granted around 1894.

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