Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678978, here are decompositions:

31 + 8678947 = 8678978
37 + 8678941 = 8678978
79 + 8678899 = 8678978
127 + 8678851 = 8678978
157 + 8678821 = 8678978
199 + 8678779 = 8678978
229 + 8678749 = 8678978
271 + 8678707 = 8678978

Showing the first eight; more decompositions exist.
