Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643708, here are decompositions:

11 + 8643697 = 8643708
37 + 8643671 = 8643708
61 + 8643647 = 8643708
89 + 8643619 = 8643708
131 + 8643577 = 8643708
181 + 8643527 = 8643708
251 + 8643457 = 8643708
349 + 8643359 = 8643708

Showing the first eight; more decompositions exist.
