Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56556, here are decompositions:

13 + 56543 = 56556
23 + 56533 = 56556
29 + 56527 = 56556
37 + 56519 = 56556
47 + 56509 = 56556
53 + 56503 = 56556
67 + 56489 = 56556
79 + 56477 = 56556

Showing the first eight; more decompositions exist.
