Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593784, here are decompositions:

17 + 31593767 = 31593784
137 + 31593647 = 31593784
251 + 31593533 = 31593784
281 + 31593503 = 31593784
293 + 31593491 = 31593784
347 + 31593437 = 31593784
587 + 31593197 = 31593784
773 + 31593011 = 31593784

Showing the first eight; more decompositions exist.
