Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624418, here are decompositions:

107 + 8624311 = 8624418
151 + 8624267 = 8624418
167 + 8624251 = 8624418
181 + 8624237 = 8624418
197 + 8624221 = 8624418
227 + 8624191 = 8624418
239 + 8624179 = 8624418
241 + 8624177 = 8624418

Showing the first eight; more decompositions exist.
