Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660988, here are decompositions:

5 + 8660983 = 8660988
19 + 8660969 = 8660988
41 + 8660947 = 8660988
59 + 8660929 = 8660988
67 + 8660921 = 8660988
79 + 8660909 = 8660988
97 + 8660891 = 8660988
101 + 8660887 = 8660988

Showing the first eight; more decompositions exist.
