Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718806, here are decompositions:

3 + 8718803 = 8718806
7 + 8718799 = 8718806
13 + 8718793 = 8718806
73 + 8718733 = 8718806
79 + 8718727 = 8718806
97 + 8718709 = 8718806
157 + 8718649 = 8718806
337 + 8718469 = 8718806

Showing the first eight; more decompositions exist.
