Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624278, here are decompositions:

11 + 8624267 = 8624278
29 + 8624249 = 8624278
41 + 8624237 = 8624278
101 + 8624177 = 8624278
137 + 8624141 = 8624278
149 + 8624129 = 8624278
167 + 8624111 = 8624278
227 + 8624051 = 8624278

Showing the first eight; more decompositions exist.
