Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718916, here are decompositions:

29 + 8718887 = 8718916
47 + 8718869 = 8718916
83 + 8718833 = 8718916
113 + 8718803 = 8718916
137 + 8718779 = 8718916
179 + 8718737 = 8718916
509 + 8718407 = 8718916
719 + 8718197 = 8718916

Showing the first eight; more decompositions exist.
