Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643268, here are decompositions:

59 + 8643209 = 8643268
71 + 8643197 = 8643268
131 + 8643137 = 8643268
191 + 8643077 = 8643268
317 + 8642951 = 8643268
419 + 8642849 = 8643268
449 + 8642819 = 8643268
521 + 8642747 = 8643268

Showing the first eight; more decompositions exist.
