Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7968, here are decompositions:

5 + 7963 = 7968
17 + 7951 = 7968
19 + 7949 = 7968
31 + 7937 = 7968
41 + 7927 = 7968
61 + 7907 = 7968
67 + 7901 = 7968
89 + 7879 = 7968

Showing the first eight; more decompositions exist.
