Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520016, here are decompositions:

19 + 519997 = 520016
73 + 519943 = 520016
97 + 519919 = 520016
109 + 519907 = 520016
127 + 519889 = 520016
199 + 519817 = 520016
223 + 519793 = 520016
229 + 519787 = 520016

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 520,016 and was likely granted around 1894.

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