Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2948, here are decompositions:

31 + 2917 = 2948
61 + 2887 = 2948
97 + 2851 = 2948
151 + 2797 = 2948
157 + 2791 = 2948
181 + 2767 = 2948
199 + 2749 = 2948
229 + 2719 = 2948

Showing the first eight; more decompositions exist.
