Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593660, here are decompositions:

13 + 31593647 = 31593660
17 + 31593643 = 31593660
19 + 31593641 = 31593660
29 + 31593631 = 31593660
31 + 31593629 = 31593660
47 + 31593613 = 31593660
53 + 31593607 = 31593660
71 + 31593589 = 31593660

Showing the first eight; more decompositions exist.
