Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593642, here are decompositions:

11 + 31593631 = 31593642
13 + 31593629 = 31593642
29 + 31593613 = 31593642
53 + 31593589 = 31593642
71 + 31593571 = 31593642
79 + 31593563 = 31593642
89 + 31593553 = 31593642
109 + 31593533 = 31593642

Showing the first eight; more decompositions exist.
