Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621682, here are decompositions:

5 + 8621677 = 8621682
29 + 8621653 = 8621682
59 + 8621623 = 8621682
73 + 8621609 = 8621682
101 + 8621581 = 8621682
131 + 8621551 = 8621682
191 + 8621491 = 8621682
229 + 8621453 = 8621682

Showing the first eight; more decompositions exist.
