Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8970, here are decompositions:

7 + 8963 = 8970
19 + 8951 = 8970
29 + 8941 = 8970
37 + 8933 = 8970
41 + 8929 = 8970
47 + 8923 = 8970
83 + 8887 = 8970
103 + 8867 = 8970

Showing the first eight; more decompositions exist.
