Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643606, here are decompositions:

17 + 8643589 = 8643606
19 + 8643587 = 8643606
29 + 8643577 = 8643606
43 + 8643563 = 8643606
67 + 8643539 = 8643606
79 + 8643527 = 8643606
149 + 8643457 = 8643606
163 + 8643443 = 8643606

Showing the first eight; more decompositions exist.
