Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678916, here are decompositions:

13 + 8678903 = 8678916
17 + 8678899 = 8678916
23 + 8678893 = 8678916
53 + 8678863 = 8678916
83 + 8678833 = 8678916
137 + 8678779 = 8678916
139 + 8678777 = 8678916
157 + 8678759 = 8678916

Showing the first eight; more decompositions exist.
