Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505510, here are decompositions:

17 + 505493 = 505510
29 + 505481 = 505510
41 + 505469 = 505510
101 + 505409 = 505510
191 + 505319 = 505510
197 + 505313 = 505510
227 + 505283 = 505510
233 + 505277 = 505510

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 505,510 and was likely granted around 1893.

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