Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500000, here are decompositions:

31 + 499969 = 500000
43 + 499957 = 500000
73 + 499927 = 500000
97 + 499903 = 500000
103 + 499897 = 500000
181 + 499819 = 500000
199 + 499801 = 500000
271 + 499729 = 500000

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 500,000 and was likely granted around 1893.

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