Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593794, here are decompositions:

7 + 31593787 = 31593794
31 + 31593763 = 31593794
73 + 31593721 = 31593794
151 + 31593643 = 31593794
163 + 31593631 = 31593794
181 + 31593613 = 31593794
223 + 31593571 = 31593794
241 + 31593553 = 31593794

Showing the first eight; more decompositions exist.
