Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2966, here are decompositions:

3 + 2963 = 2966
13 + 2953 = 2966
79 + 2887 = 2966
109 + 2857 = 2966
163 + 2803 = 2966
199 + 2767 = 2966
277 + 2689 = 2966
283 + 2683 = 2966

Showing the first eight; more decompositions exist.
