Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718836, here are decompositions:

3 + 8718833 = 8718836
13 + 8718823 = 8718836
37 + 8718799 = 8718836
43 + 8718793 = 8718836
79 + 8718757 = 8718836
103 + 8718733 = 8718836
109 + 8718727 = 8718836
127 + 8718709 = 8718836

Showing the first eight; more decompositions exist.
