Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678856, here are decompositions:

5 + 8678851 = 8678856
23 + 8678833 = 8678856
73 + 8678783 = 8678856
79 + 8678777 = 8678856
83 + 8678773 = 8678856
97 + 8678759 = 8678856
103 + 8678753 = 8678856
107 + 8678749 = 8678856

Showing the first eight; more decompositions exist.
