Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28566, here are decompositions:

7 + 28559 = 28566
17 + 28549 = 28566
19 + 28547 = 28566
29 + 28537 = 28566
53 + 28513 = 28566
67 + 28499 = 28566
73 + 28493 = 28566
89 + 28477 = 28566

Showing the first eight; more decompositions exist.
