Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678862, here are decompositions:

11 + 8678851 = 8678862
29 + 8678833 = 8678862
41 + 8678821 = 8678862
79 + 8678783 = 8678862
83 + 8678779 = 8678862
89 + 8678773 = 8678862
103 + 8678759 = 8678862
109 + 8678753 = 8678862

Showing the first eight; more decompositions exist.
