Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718960, here are decompositions:

7 + 8718953 = 8718960
11 + 8718949 = 8718960
43 + 8718917 = 8718960
53 + 8718907 = 8718960
73 + 8718887 = 8718960
79 + 8718881 = 8718960
83 + 8718877 = 8718960
101 + 8718859 = 8718960

Showing the first eight; more decompositions exist.
