Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30948, here are decompositions:

7 + 30941 = 30948
11 + 30937 = 30948
17 + 30931 = 30948
37 + 30911 = 30948
67 + 30881 = 30948
79 + 30869 = 30948
89 + 30859 = 30948
97 + 30851 = 30948

Showing the first eight; more decompositions exist.
