Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593708, here are decompositions:

5 + 31593703 = 31593708
19 + 31593689 = 31593708
61 + 31593647 = 31593708
67 + 31593641 = 31593708
79 + 31593629 = 31593708
101 + 31593607 = 31593708
137 + 31593571 = 31593708
191 + 31593517 = 31593708

Showing the first eight; more decompositions exist.
