Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10566, here are decompositions:

7 + 10559 = 10566
37 + 10529 = 10566
53 + 10513 = 10566
67 + 10499 = 10566
79 + 10487 = 10566
89 + 10477 = 10566
103 + 10463 = 10566
107 + 10459 = 10566

Showing the first eight; more decompositions exist.
