Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717664, here are decompositions:

31 + 8717633 = 8717664
41 + 8717623 = 8717664
73 + 8717591 = 8717664
101 + 8717563 = 8717664
107 + 8717557 = 8717664
113 + 8717551 = 8717664
173 + 8717491 = 8717664
271 + 8717393 = 8717664

Showing the first eight; more decompositions exist.
