Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628828, here are decompositions:

17 + 8628811 = 8628828
29 + 8628799 = 8628828
37 + 8628791 = 8628828
41 + 8628787 = 8628828
101 + 8628727 = 8628828
151 + 8628677 = 8628828
167 + 8628661 = 8628828
181 + 8628647 = 8628828

Showing the first eight; more decompositions exist.
