Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643684, here are decompositions:

11 + 8643673 = 8643684
13 + 8643671 = 8643684
37 + 8643647 = 8643684
53 + 8643631 = 8643684
97 + 8643587 = 8643684
107 + 8643577 = 8643684
157 + 8643527 = 8643684
163 + 8643521 = 8643684

Showing the first eight; more decompositions exist.
