Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3668, here are decompositions:

31 + 3637 = 3668
37 + 3631 = 3668
61 + 3607 = 3668
97 + 3571 = 3668
109 + 3559 = 3668
127 + 3541 = 3668
139 + 3529 = 3668
151 + 3517 = 3668

Showing the first eight; more decompositions exist.
