Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593736, here are decompositions:

17 + 31593719 = 31593736
47 + 31593689 = 31593736
89 + 31593647 = 31593736
107 + 31593629 = 31593736
173 + 31593563 = 31593736
233 + 31593503 = 31593736
257 + 31593479 = 31593736
347 + 31593389 = 31593736

Showing the first eight; more decompositions exist.
