Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3944, here are decompositions:

13 + 3931 = 3944
37 + 3907 = 3944
67 + 3877 = 3944
97 + 3847 = 3944
151 + 3793 = 3944
211 + 3733 = 3944
271 + 3673 = 3944
307 + 3637 = 3944

Showing the first eight; more decompositions exist.
