Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647724, here are decompositions:

13 + 8647711 = 8647724
67 + 8647657 = 8647724
157 + 8647567 = 8647724
193 + 8647531 = 8647724
223 + 8647501 = 8647724
277 + 8647447 = 8647724
307 + 8647417 = 8647724
313 + 8647411 = 8647724

Showing the first eight; more decompositions exist.
