Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505000, here are decompositions:

11 + 504989 = 505000
17 + 504983 = 505000
47 + 504953 = 505000
53 + 504947 = 505000
71 + 504929 = 505000
107 + 504893 = 505000
149 + 504851 = 505000
179 + 504821 = 505000

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 505,000 and was likely granted around 1893.

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