Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593658, here are decompositions:

11 + 31593647 = 31593658
17 + 31593641 = 31593658
29 + 31593629 = 31593658
167 + 31593491 = 31593658
179 + 31593479 = 31593658
197 + 31593461 = 31593658
269 + 31593389 = 31593658
281 + 31593377 = 31593658

Showing the first eight; more decompositions exist.
