Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500020, here are decompositions:

11 + 500009 = 500020
41 + 499979 = 500020
47 + 499973 = 500020
137 + 499883 = 500020
167 + 499853 = 500020
233 + 499787 = 500020
239 + 499781 = 500020
281 + 499739 = 500020

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 500,020 and was likely granted around 1893.

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