Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605668, here are decompositions:

31 + 8605637 = 8605668
59 + 8605609 = 8605668
61 + 8605607 = 8605668
67 + 8605601 = 8605668
101 + 8605567 = 8605668
107 + 8605561 = 8605668
139 + 8605529 = 8605668
157 + 8605511 = 8605668

Showing the first eight; more decompositions exist.
