Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502020, here are decompositions:

7 + 502013 = 502020
19 + 502001 = 502020
23 + 501997 = 502020
53 + 501967 = 502020
67 + 501953 = 502020
73 + 501947 = 502020
89 + 501931 = 502020
109 + 501911 = 502020

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 502,020 and was likely granted around 1893.

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