Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678216, here are decompositions:

3 + 8678213 = 8678216
13 + 8678203 = 8678216
37 + 8678179 = 8678216
67 + 8678149 = 8678216
103 + 8678113 = 8678216
163 + 8678053 = 8678216
223 + 8677993 = 8678216
457 + 8677759 = 8678216

Showing the first eight; more decompositions exist.
