Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2946, here are decompositions:

7 + 2939 = 2946
19 + 2927 = 2946
29 + 2917 = 2946
37 + 2909 = 2946
43 + 2903 = 2946
59 + 2887 = 2946
67 + 2879 = 2946
89 + 2857 = 2946

Showing the first eight; more decompositions exist.
