Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593616, here are decompositions:

3 + 31593613 = 31593616
53 + 31593563 = 31593616
83 + 31593533 = 31593616
113 + 31593503 = 31593616
137 + 31593479 = 31593616
179 + 31593437 = 31593616
227 + 31593389 = 31593616
239 + 31593377 = 31593616

Showing the first eight; more decompositions exist.
