Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2980, here are decompositions:

11 + 2969 = 2980
17 + 2963 = 2980
23 + 2957 = 2980
41 + 2939 = 2980
53 + 2927 = 2980
71 + 2909 = 2980
83 + 2897 = 2980
101 + 2879 = 2980

Showing the first eight; more decompositions exist.
