Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718868, here are decompositions:

17 + 8718851 = 8718868
29 + 8718839 = 8718868
71 + 8718797 = 8718868
89 + 8718779 = 8718868
131 + 8718737 = 8718868
449 + 8718419 = 8718868
461 + 8718407 = 8718868
467 + 8718401 = 8718868

Showing the first eight; more decompositions exist.
