Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620982, here are decompositions:

31 + 8620951 = 8620982
109 + 8620873 = 8620982
379 + 8620603 = 8620982
439 + 8620543 = 8620982
613 + 8620369 = 8620982
751 + 8620231 = 8620982
823 + 8620159 = 8620982
919 + 8620063 = 8620982

Showing the first eight; more decompositions exist.
