Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621022, here are decompositions:

5 + 8621017 = 8621022
13 + 8621009 = 8621022
29 + 8620993 = 8621022
71 + 8620951 = 8621022
73 + 8620949 = 8621022
79 + 8620943 = 8621022
149 + 8620873 = 8621022
181 + 8620841 = 8621022

Showing the first eight; more decompositions exist.
