Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520002, here are decompositions:

5 + 519997 = 520002
13 + 519989 = 520002
31 + 519971 = 520002
59 + 519943 = 520002
71 + 519931 = 520002
79 + 519923 = 520002
83 + 519919 = 520002
113 + 519889 = 520002

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 520,002 and was likely granted around 1894.

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