Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505656, here are decompositions:

13 + 505643 = 505656
17 + 505639 = 505656
23 + 505633 = 505656
37 + 505619 = 505656
43 + 505613 = 505656
83 + 505573 = 505656
97 + 505559 = 505656
163 + 505493 = 505656

Showing the first eight; more decompositions exist.
