Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717640, here are decompositions:

7 + 8717633 = 8717640
17 + 8717623 = 8717640
83 + 8717557 = 8717640
89 + 8717551 = 8717640
109 + 8717531 = 8717640
131 + 8717509 = 8717640
149 + 8717491 = 8717640
251 + 8717389 = 8717640

Showing the first eight; more decompositions exist.
