Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593712, here are decompositions:

23 + 31593689 = 31593712
71 + 31593641 = 31593712
83 + 31593629 = 31593712
149 + 31593563 = 31593712
179 + 31593533 = 31593712
233 + 31593479 = 31593712
251 + 31593461 = 31593712
461 + 31593251 = 31593712

Showing the first eight; more decompositions exist.
