Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593956, here are decompositions:

3 + 31593953 = 31593956
13 + 31593943 = 31593956
19 + 31593937 = 31593956
193 + 31593763 = 31593956
313 + 31593643 = 31593956
349 + 31593607 = 31593956
367 + 31593589 = 31593956
439 + 31593517 = 31593956

Showing the first eight; more decompositions exist.
