Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593752, here are decompositions:

31 + 31593721 = 31593752
109 + 31593643 = 31593752
139 + 31593613 = 31593752
163 + 31593589 = 31593752
181 + 31593571 = 31593752
199 + 31593553 = 31593752
241 + 31593511 = 31593752
409 + 31593343 = 31593752

Showing the first eight; more decompositions exist.
