Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699970, here are decompositions:

11 + 8699959 = 8699970
17 + 8699953 = 8699970
23 + 8699947 = 8699970
47 + 8699923 = 8699970
53 + 8699917 = 8699970
113 + 8699857 = 8699970
157 + 8699813 = 8699970
163 + 8699807 = 8699970

Showing the first eight; more decompositions exist.
