Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3738, here are decompositions:

5 + 3733 = 3738
11 + 3727 = 3738
19 + 3719 = 3738
29 + 3709 = 3738
37 + 3701 = 3738
41 + 3697 = 3738
47 + 3691 = 3738
61 + 3677 = 3738

Showing the first eight; more decompositions exist.
