Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678244, here are decompositions:

7 + 8678237 = 8678244
31 + 8678213 = 8678244
41 + 8678203 = 8678244
83 + 8678161 = 8678244
97 + 8678147 = 8678244
103 + 8678141 = 8678244
131 + 8678113 = 8678244
151 + 8678093 = 8678244

Showing the first eight; more decompositions exist.
