Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643724, here are decompositions:

3 + 8643721 = 8643724
17 + 8643707 = 8643724
53 + 8643671 = 8643724
137 + 8643587 = 8643724
197 + 8643527 = 8643724
281 + 8643443 = 8643724
443 + 8643281 = 8643724
587 + 8643137 = 8643724

Showing the first eight; more decompositions exist.
