Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631724, here are decompositions:

11 + 8631713 = 8631724
107 + 8631617 = 8631724
113 + 8631611 = 8631724
191 + 8631533 = 8631724
383 + 8631341 = 8631724
557 + 8631167 = 8631724
641 + 8631083 = 8631724
683 + 8631041 = 8631724

Showing the first eight; more decompositions exist.
