Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678970, here are decompositions:

7 + 8678963 = 8678970
19 + 8678951 = 8678970
23 + 8678947 = 8678970
29 + 8678941 = 8678970
31 + 8678939 = 8678970
37 + 8678933 = 8678970
43 + 8678927 = 8678970
67 + 8678903 = 8678970

Showing the first eight; more decompositions exist.
