Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659568, here are decompositions:

31 + 8659537 = 8659568
37 + 8659531 = 8659568
67 + 8659501 = 8659568
97 + 8659471 = 8659568
349 + 8659219 = 8659568
571 + 8658997 = 8659568
607 + 8658961 = 8659568
691 + 8658877 = 8659568

Showing the first eight; more decompositions exist.
