Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3560, here are decompositions:

3 + 3557 = 3560
13 + 3547 = 3560
19 + 3541 = 3560
31 + 3529 = 3560
43 + 3517 = 3560
61 + 3499 = 3560
97 + 3463 = 3560
103 + 3457 = 3560

Showing the first eight; more decompositions exist.
