Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2958, here are decompositions:

5 + 2953 = 2958
19 + 2939 = 2958
31 + 2927 = 2958
41 + 2917 = 2958
61 + 2897 = 2958
71 + 2887 = 2958
79 + 2879 = 2958
97 + 2861 = 2958

Showing the first eight; more decompositions exist.
