Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3688, here are decompositions:

11 + 3677 = 3688
17 + 3671 = 3688
29 + 3659 = 3688
71 + 3617 = 3688
107 + 3581 = 3688
131 + 3557 = 3688
149 + 3539 = 3688
197 + 3491 = 3688

Showing the first eight; more decompositions exist.
