Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2970, here are decompositions:

7 + 2963 = 2970
13 + 2957 = 2970
17 + 2953 = 2970
31 + 2939 = 2970
43 + 2927 = 2970
53 + 2917 = 2970
61 + 2909 = 2970
67 + 2903 = 2970

Showing the first eight; more decompositions exist.
