Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2988, here are decompositions:

17 + 2971 = 2988
19 + 2969 = 2988
31 + 2957 = 2988
61 + 2927 = 2988
71 + 2917 = 2988
79 + 2909 = 2988
101 + 2887 = 2988
109 + 2879 = 2988

Showing the first eight; more decompositions exist.
