Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700970, here are decompositions:

17 + 8700953 = 8700970
23 + 8700947 = 8700970
29 + 8700941 = 8700970
59 + 8700911 = 8700970
101 + 8700869 = 8700970
137 + 8700833 = 8700970
197 + 8700773 = 8700970
389 + 8700581 = 8700970

Showing the first eight; more decompositions exist.
