Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624218, here are decompositions:

17 + 8624201 = 8624218
41 + 8624177 = 8624218
59 + 8624159 = 8624218
89 + 8624129 = 8624218
107 + 8624111 = 8624218
167 + 8624051 = 8624218
191 + 8624027 = 8624218
257 + 8623961 = 8624218

Showing the first eight; more decompositions exist.
