Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718834, here are decompositions:

11 + 8718823 = 8718834
23 + 8718811 = 8718834
31 + 8718803 = 8718834
37 + 8718797 = 8718834
41 + 8718793 = 8718834
97 + 8718737 = 8718834
101 + 8718733 = 8718834
107 + 8718727 = 8718834

Showing the first eight; more decompositions exist.
