Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621108, here are decompositions:

7 + 8621101 = 8621108
19 + 8621089 = 8621108
31 + 8621077 = 8621108
61 + 8621047 = 8621108
157 + 8620951 = 8621108
211 + 8620897 = 8621108
421 + 8620687 = 8621108
487 + 8620621 = 8621108

Showing the first eight; more decompositions exist.
