Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593724, here are decompositions:

3 + 31593721 = 31593724
5 + 31593719 = 31593724
83 + 31593641 = 31593724
191 + 31593533 = 31593724
233 + 31593491 = 31593724
263 + 31593461 = 31593724
347 + 31593377 = 31593724
677 + 31593047 = 31593724

Showing the first eight; more decompositions exist.
