Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593738, here are decompositions:

17 + 31593721 = 31593738
19 + 31593719 = 31593738
97 + 31593641 = 31593738
107 + 31593631 = 31593738
109 + 31593629 = 31593738
131 + 31593607 = 31593738
149 + 31593589 = 31593738
167 + 31593571 = 31593738

Showing the first eight; more decompositions exist.
