Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593624, here are decompositions:

11 + 31593613 = 31593624
17 + 31593607 = 31593624
53 + 31593571 = 31593624
61 + 31593563 = 31593624
71 + 31593553 = 31593624
107 + 31593517 = 31593624
113 + 31593511 = 31593624
163 + 31593461 = 31593624

Showing the first eight; more decompositions exist.
