Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593568, here are decompositions:

5 + 31593563 = 31593568
89 + 31593479 = 31593568
107 + 31593461 = 31593568
131 + 31593437 = 31593568
179 + 31593389 = 31593568
191 + 31593377 = 31593568
269 + 31593299 = 31593568
317 + 31593251 = 31593568

Showing the first eight; more decompositions exist.
