Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660970, here are decompositions:

23 + 8660947 = 8660970
37 + 8660933 = 8660970
41 + 8660929 = 8660970
61 + 8660909 = 8660970
79 + 8660891 = 8660970
83 + 8660887 = 8660970
107 + 8660863 = 8660970
151 + 8660819 = 8660970

Showing the first eight; more decompositions exist.
