Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593756, here are decompositions:

37 + 31593719 = 31593756
53 + 31593703 = 31593756
67 + 31593689 = 31593756
109 + 31593647 = 31593756
113 + 31593643 = 31593756
127 + 31593629 = 31593756
149 + 31593607 = 31593756
167 + 31593589 = 31593756

Showing the first eight; more decompositions exist.
