Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593772, here are decompositions:

5 + 31593767 = 31593772
53 + 31593719 = 31593772
83 + 31593689 = 31593772
131 + 31593641 = 31593772
239 + 31593533 = 31593772
269 + 31593503 = 31593772
281 + 31593491 = 31593772
293 + 31593479 = 31593772

Showing the first eight; more decompositions exist.
