Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621634, here are decompositions:

11 + 8621623 = 8621634
17 + 8621617 = 8621634
53 + 8621581 = 8621634
83 + 8621551 = 8621634
157 + 8621477 = 8621634
167 + 8621467 = 8621634
181 + 8621453 = 8621634
191 + 8621443 = 8621634

Showing the first eight; more decompositions exist.
