Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628756, here are decompositions:

5 + 8628751 = 8628756
29 + 8628727 = 8628756
47 + 8628709 = 8628756
79 + 8628677 = 8628756
109 + 8628647 = 8628756
113 + 8628643 = 8628756
127 + 8628629 = 8628756
263 + 8628493 = 8628756

Showing the first eight; more decompositions exist.
