Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658726, here are decompositions:

17 + 8658709 = 8658726
29 + 8658697 = 8658726
47 + 8658679 = 8658726
53 + 8658673 = 8658726
67 + 8658659 = 8658726
73 + 8658653 = 8658726
107 + 8658619 = 8658726
113 + 8658613 = 8658726

Showing the first eight; more decompositions exist.
