Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620662, here are decompositions:

23 + 8620639 = 8620662
31 + 8620631 = 8620662
41 + 8620621 = 8620662
59 + 8620603 = 8620662
73 + 8620589 = 8620662
109 + 8620553 = 8620662
163 + 8620499 = 8620662
233 + 8620429 = 8620662

Showing the first eight; more decompositions exist.
