Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56566, here are decompositions:

23 + 56543 = 56566
47 + 56519 = 56566
89 + 56477 = 56566
113 + 56453 = 56566
149 + 56417 = 56566
173 + 56393 = 56566
197 + 56369 = 56566
233 + 56333 = 56566

Showing the first eight; more decompositions exist.
