Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678810, here are decompositions:

31 + 8678779 = 8678810
37 + 8678773 = 8678810
61 + 8678749 = 8678810
97 + 8678713 = 8678810
103 + 8678707 = 8678810
109 + 8678701 = 8678810
139 + 8678671 = 8678810
211 + 8678599 = 8678810

Showing the first eight; more decompositions exist.
