Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565530, here are decompositions:

11 + 565519 = 565530
13 + 565517 = 565530
19 + 565511 = 565530
23 + 565507 = 565530
41 + 565489 = 565530
47 + 565483 = 565530
61 + 565469 = 565530
67 + 565463 = 565530

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 565,530 and was likely granted around 1895.

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