Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520006, here are decompositions:

17 + 519989 = 520006
59 + 519947 = 520006
83 + 519923 = 520006
89 + 519917 = 520006
269 + 519737 = 520006
293 + 519713 = 520006
359 + 519647 = 520006
419 + 519587 = 520006

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 520,006 and was likely granted around 1894.

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