Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3654, here are decompositions:

11 + 3643 = 3654
17 + 3637 = 3654
23 + 3631 = 3654
31 + 3623 = 3654
37 + 3617 = 3654
41 + 3613 = 3654
47 + 3607 = 3654
61 + 3593 = 3654

Showing the first eight; more decompositions exist.
