Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2976, here are decompositions:

5 + 2971 = 2976
7 + 2969 = 2976
13 + 2963 = 2976
19 + 2957 = 2976
23 + 2953 = 2976
37 + 2939 = 2976
59 + 2917 = 2976
67 + 2909 = 2976

Showing the first eight; more decompositions exist.
