Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3756, here are decompositions:

17 + 3739 = 3756
23 + 3733 = 3756
29 + 3727 = 3756
37 + 3719 = 3756
47 + 3709 = 3756
59 + 3697 = 3756
79 + 3677 = 3756
83 + 3673 = 3756

Showing the first eight; more decompositions exist.
