Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678790, here are decompositions:

7 + 8678783 = 8678790
11 + 8678779 = 8678790
13 + 8678777 = 8678790
17 + 8678773 = 8678790
31 + 8678759 = 8678790
37 + 8678753 = 8678790
41 + 8678749 = 8678790
83 + 8678707 = 8678790

Showing the first eight; more decompositions exist.
