Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661960, here are decompositions:

7 + 8661953 = 8661960
17 + 8661943 = 8661960
19 + 8661941 = 8661960
59 + 8661901 = 8661960
61 + 8661899 = 8661960
71 + 8661889 = 8661960
79 + 8661881 = 8661960
89 + 8661871 = 8661960

Showing the first eight; more decompositions exist.
