Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657864, here are decompositions:

13 + 8657851 = 8657864
31 + 8657833 = 8657864
37 + 8657827 = 8657864
97 + 8657767 = 8657864
307 + 8657557 = 8657864
331 + 8657533 = 8657864
433 + 8657431 = 8657864
487 + 8657377 = 8657864

Showing the first eight; more decompositions exist.
