Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718756, here are decompositions:

19 + 8718737 = 8718756
23 + 8718733 = 8718756
29 + 8718727 = 8718756
47 + 8718709 = 8718756
83 + 8718673 = 8718756
107 + 8718649 = 8718756
269 + 8718487 = 8718756
317 + 8718439 = 8718756

Showing the first eight; more decompositions exist.
