Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624928, here are decompositions:

7 + 8624921 = 8624928
41 + 8624887 = 8624928
47 + 8624881 = 8624928
107 + 8624821 = 8624928
157 + 8624771 = 8624928
211 + 8624717 = 8624928
251 + 8624677 = 8624928
307 + 8624621 = 8624928

Showing the first eight; more decompositions exist.
