Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690970, here are decompositions:

7 + 8690963 = 8690970
11 + 8690959 = 8690970
17 + 8690953 = 8690970
19 + 8690951 = 8690970
23 + 8690947 = 8690970
53 + 8690917 = 8690970
103 + 8690867 = 8690970
149 + 8690821 = 8690970

Showing the first eight; more decompositions exist.
