Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742724, here are decompositions:

47 + 8742677 = 8742724
71 + 8742653 = 8742724
101 + 8742623 = 8742724
173 + 8742551 = 8742724
227 + 8742497 = 8742724
461 + 8742263 = 8742724
563 + 8742161 = 8742724
647 + 8742077 = 8742724

Showing the first eight; more decompositions exist.
