Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718736, here are decompositions:

3 + 8718733 = 8718736
197 + 8718539 = 8718736
233 + 8718503 = 8718736
317 + 8718419 = 8718736
359 + 8718377 = 8718736
647 + 8718089 = 8718736
743 + 8717993 = 8718736
773 + 8717963 = 8718736

Showing the first eight; more decompositions exist.
