Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593774, here are decompositions:

7 + 31593767 = 31593774
11 + 31593763 = 31593774
53 + 31593721 = 31593774
71 + 31593703 = 31593774
127 + 31593647 = 31593774
131 + 31593643 = 31593774
167 + 31593607 = 31593774
211 + 31593563 = 31593774

Showing the first eight; more decompositions exist.
