Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593742, here are decompositions:

23 + 31593719 = 31593742
53 + 31593689 = 31593742
101 + 31593641 = 31593742
113 + 31593629 = 31593742
179 + 31593563 = 31593742
239 + 31593503 = 31593742
251 + 31593491 = 31593742
263 + 31593479 = 31593742

Showing the first eight; more decompositions exist.
