Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641682, here are decompositions:

13 + 8641669 = 8641682
31 + 8641651 = 8641682
61 + 8641621 = 8641682
79 + 8641603 = 8641682
139 + 8641543 = 8641682
163 + 8641519 = 8641682
211 + 8641471 = 8641682
229 + 8641453 = 8641682

Showing the first eight; more decompositions exist.
