Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3672, here are decompositions:

13 + 3659 = 3672
29 + 3643 = 3672
41 + 3631 = 3672
59 + 3613 = 3672
79 + 3593 = 3672
89 + 3583 = 3672
101 + 3571 = 3672
113 + 3559 = 3672

Showing the first eight; more decompositions exist.
