Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678218, here are decompositions:

5 + 8678213 = 8678218
71 + 8678147 = 8678218
89 + 8678129 = 8678218
137 + 8678081 = 8678218
149 + 8678069 = 8678218
167 + 8678051 = 8678218
179 + 8678039 = 8678218
191 + 8678027 = 8678218

Showing the first eight; more decompositions exist.
