Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621064, here are decompositions:

13 + 8621051 = 8621064
17 + 8621047 = 8621064
47 + 8621017 = 8621064
71 + 8620993 = 8621064
113 + 8620951 = 8621064
167 + 8620897 = 8621064
191 + 8620873 = 8621064
223 + 8620841 = 8621064

Showing the first eight; more decompositions exist.
