Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3566, here are decompositions:

7 + 3559 = 3566
19 + 3547 = 3566
37 + 3529 = 3566
67 + 3499 = 3566
97 + 3469 = 3566
103 + 3463 = 3566
109 + 3457 = 3566
193 + 3373 = 3566

Showing the first eight; more decompositions exist.
