Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620668, here are decompositions:

5 + 8620663 = 8620668
29 + 8620639 = 8620668
31 + 8620637 = 8620668
37 + 8620631 = 8620668
47 + 8620621 = 8620668
79 + 8620589 = 8620668
97 + 8620571 = 8620668
101 + 8620567 = 8620668

Showing the first eight; more decompositions exist.
