Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628716, here are decompositions:

7 + 8628709 = 8628716
73 + 8628643 = 8628716
163 + 8628553 = 8628716
223 + 8628493 = 8628716
367 + 8628349 = 8628716
619 + 8628097 = 8628716
709 + 8628007 = 8628716
739 + 8627977 = 8628716

Showing the first eight; more decompositions exist.
