Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3690, here are decompositions:

13 + 3677 = 3690
17 + 3673 = 3690
19 + 3671 = 3690
31 + 3659 = 3690
47 + 3643 = 3690
53 + 3637 = 3690
59 + 3631 = 3690
67 + 3623 = 3690

Showing the first eight; more decompositions exist.
