Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718738, here are decompositions:

5 + 8718733 = 8718738
11 + 8718727 = 8718738
29 + 8718709 = 8718738
89 + 8718649 = 8718738
137 + 8718601 = 8718738
157 + 8718581 = 8718738
167 + 8718571 = 8718738
199 + 8718539 = 8718738

Showing the first eight; more decompositions exist.
