Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718816, here are decompositions:

5 + 8718811 = 8718816
13 + 8718803 = 8718816
17 + 8718799 = 8718816
19 + 8718797 = 8718816
23 + 8718793 = 8718816
37 + 8718779 = 8718816
59 + 8718757 = 8718816
79 + 8718737 = 8718816

Showing the first eight; more decompositions exist.
