Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659970, here are decompositions:

13 + 8659957 = 8659970
31 + 8659939 = 8659970
43 + 8659927 = 8659970
61 + 8659909 = 8659970
97 + 8659873 = 8659970
103 + 8659867 = 8659970
223 + 8659747 = 8659970
229 + 8659741 = 8659970

Showing the first eight; more decompositions exist.
