Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593782, here are decompositions:

19 + 31593763 = 31593782
61 + 31593721 = 31593782
79 + 31593703 = 31593782
139 + 31593643 = 31593782
151 + 31593631 = 31593782
193 + 31593589 = 31593782
211 + 31593571 = 31593782
229 + 31593553 = 31593782

Showing the first eight; more decompositions exist.
