Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3720, here are decompositions:

11 + 3709 = 3720
19 + 3701 = 3720
23 + 3697 = 3720
29 + 3691 = 3720
43 + 3677 = 3720
47 + 3673 = 3720
61 + 3659 = 3720
83 + 3637 = 3720

Showing the first eight; more decompositions exist.
