Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711640, here are decompositions:

13 + 8711627 = 8711640
19 + 8711621 = 8711640
23 + 8711617 = 8711640
37 + 8711603 = 8711640
71 + 8711569 = 8711640
79 + 8711561 = 8711640
89 + 8711551 = 8711640
97 + 8711543 = 8711640

Showing the first eight; more decompositions exist.
