Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3996, here are decompositions:

7 + 3989 = 3996
29 + 3967 = 3996
53 + 3943 = 3996
67 + 3929 = 3996
73 + 3923 = 3996
79 + 3917 = 3996
89 + 3907 = 3996
107 + 3889 = 3996

Showing the first eight; more decompositions exist.
