Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593732, here are decompositions:

11 + 31593721 = 31593732
13 + 31593719 = 31593732
29 + 31593703 = 31593732
43 + 31593689 = 31593732
89 + 31593643 = 31593732
101 + 31593631 = 31593732
103 + 31593629 = 31593732
179 + 31593553 = 31593732

Showing the first eight; more decompositions exist.
