Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2950, here are decompositions:

11 + 2939 = 2950
23 + 2927 = 2950
41 + 2909 = 2950
47 + 2903 = 2950
53 + 2897 = 2950
71 + 2879 = 2950
89 + 2861 = 2950
107 + 2843 = 2950

Showing the first eight; more decompositions exist.
