Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3970, here are decompositions:

3 + 3967 = 3970
23 + 3947 = 3970
41 + 3929 = 3970
47 + 3923 = 3970
53 + 3917 = 3970
59 + 3911 = 3970
89 + 3881 = 3970
107 + 3863 = 3970

Showing the first eight; more decompositions exist.
