Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520000, here are decompositions:

3 + 519997 = 520000
11 + 519989 = 520000
29 + 519971 = 520000
53 + 519947 = 520000
83 + 519917 = 520000
137 + 519863 = 520000
197 + 519803 = 520000
263 + 519737 = 520000

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 520,000 and was likely granted around 1894.

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