Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7960, here are decompositions:

11 + 7949 = 7960
23 + 7937 = 7960
41 + 7919 = 7960
53 + 7907 = 7960
59 + 7901 = 7960
83 + 7877 = 7960
107 + 7853 = 7960
131 + 7829 = 7960

Showing the first eight; more decompositions exist.
