Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628774, here are decompositions:

23 + 8628751 = 8628774
47 + 8628727 = 8628774
97 + 8628677 = 8628774
113 + 8628661 = 8628774
127 + 8628647 = 8628774
131 + 8628643 = 8628774
151 + 8628623 = 8628774
173 + 8628601 = 8628774

Showing the first eight; more decompositions exist.
