Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4038, here are decompositions:

11 + 4027 = 4038
17 + 4021 = 4038
19 + 4019 = 4038
31 + 4007 = 4038
37 + 4001 = 4038
71 + 3967 = 4038
107 + 3931 = 4038
109 + 3929 = 4038

Showing the first eight; more decompositions exist.
