Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565566, here are decompositions:

7 + 565559 = 565566
13 + 565553 = 565566
17 + 565549 = 565566
47 + 565519 = 565566
59 + 565507 = 565566
83 + 565483 = 565566
97 + 565469 = 565566
103 + 565463 = 565566

Showing the first eight; more decompositions exist.
