Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621924, here are decompositions:

13 + 8621911 = 8621924
61 + 8621863 = 8621924
67 + 8621857 = 8621924
97 + 8621827 = 8621924
127 + 8621797 = 8621924
151 + 8621773 = 8621924
271 + 8621653 = 8621924
307 + 8621617 = 8621924

Showing the first eight; more decompositions exist.
