Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678838, here are decompositions:

5 + 8678833 = 8678838
17 + 8678821 = 8678838
59 + 8678779 = 8678838
61 + 8678777 = 8678838
79 + 8678759 = 8678838
89 + 8678749 = 8678838
97 + 8678741 = 8678838
131 + 8678707 = 8678838

Showing the first eight; more decompositions exist.
