Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593550, here are decompositions:

17 + 31593533 = 31593550
47 + 31593503 = 31593550
59 + 31593491 = 31593550
71 + 31593479 = 31593550
89 + 31593461 = 31593550
113 + 31593437 = 31593550
173 + 31593377 = 31593550
251 + 31593299 = 31593550

Showing the first eight; more decompositions exist.
