Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516000, here are decompositions:

7 + 515993 = 516000
31 + 515969 = 516000
59 + 515941 = 516000
71 + 515929 = 516000
83 + 515917 = 516000
113 + 515887 = 516000
127 + 515873 = 516000
139 + 515861 = 516000

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 516,000 and was likely granted around 1894.

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