Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593882, here are decompositions:

13 + 31593869 = 31593882
43 + 31593839 = 31593882
163 + 31593719 = 31593882
179 + 31593703 = 31593882
193 + 31593689 = 31593882
239 + 31593643 = 31593882
241 + 31593641 = 31593882
251 + 31593631 = 31593882

Showing the first eight; more decompositions exist.
