Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593726, here are decompositions:

5 + 31593721 = 31593726
7 + 31593719 = 31593726
23 + 31593703 = 31593726
37 + 31593689 = 31593726
79 + 31593647 = 31593726
83 + 31593643 = 31593726
97 + 31593629 = 31593726
113 + 31593613 = 31593726

Showing the first eight; more decompositions exist.
