Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678886, here are decompositions:

23 + 8678863 = 8678886
53 + 8678833 = 8678886
103 + 8678783 = 8678886
107 + 8678779 = 8678886
109 + 8678777 = 8678886
113 + 8678773 = 8678886
127 + 8678759 = 8678886
137 + 8678749 = 8678886

Showing the first eight; more decompositions exist.
