Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742568, here are decompositions:

17 + 8742551 = 8742568
71 + 8742497 = 8742568
167 + 8742401 = 8742568
251 + 8742317 = 8742568
491 + 8742077 = 8742568
509 + 8742059 = 8742568
557 + 8742011 = 8742568
617 + 8741951 = 8742568

Showing the first eight; more decompositions exist.
