Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593702, here are decompositions:

13 + 31593689 = 31593702
59 + 31593643 = 31593702
61 + 31593641 = 31593702
71 + 31593631 = 31593702
73 + 31593629 = 31593702
89 + 31593613 = 31593702
113 + 31593589 = 31593702
131 + 31593571 = 31593702

Showing the first eight; more decompositions exist.
