Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593664, here are decompositions:

17 + 31593647 = 31593664
23 + 31593641 = 31593664
101 + 31593563 = 31593664
131 + 31593533 = 31593664
173 + 31593491 = 31593664
227 + 31593437 = 31593664
467 + 31593197 = 31593664
491 + 31593173 = 31593664

Showing the first eight; more decompositions exist.
