Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717970, here are decompositions:

7 + 8717963 = 8717970
11 + 8717959 = 8717970
31 + 8717939 = 8717970
43 + 8717927 = 8717970
61 + 8717909 = 8717970
89 + 8717881 = 8717970
97 + 8717873 = 8717970
101 + 8717869 = 8717970

Showing the first eight; more decompositions exist.
