Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658732, here are decompositions:

23 + 8658709 = 8658732
53 + 8658679 = 8658732
59 + 8658673 = 8658732
73 + 8658659 = 8658732
79 + 8658653 = 8658732
113 + 8658619 = 8658732
149 + 8658583 = 8658732
151 + 8658581 = 8658732

Showing the first eight; more decompositions exist.
