Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624238, here are decompositions:

17 + 8624221 = 8624238
37 + 8624201 = 8624238
47 + 8624191 = 8624238
59 + 8624179 = 8624238
61 + 8624177 = 8624238
79 + 8624159 = 8624238
97 + 8624141 = 8624238
101 + 8624137 = 8624238

Showing the first eight; more decompositions exist.
