Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678806, here are decompositions:

23 + 8678783 = 8678806
29 + 8678777 = 8678806
47 + 8678759 = 8678806
53 + 8678753 = 8678806
107 + 8678699 = 8678806
113 + 8678693 = 8678806
137 + 8678669 = 8678806
167 + 8678639 = 8678806

Showing the first eight; more decompositions exist.
