Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597640, here are decompositions:

11 + 8597629 = 8597640
17 + 8597623 = 8597640
19 + 8597621 = 8597640
41 + 8597599 = 8597640
53 + 8597587 = 8597640
89 + 8597551 = 8597640
109 + 8597531 = 8597640
113 + 8597527 = 8597640

Showing the first eight; more decompositions exist.
