Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593684, here are decompositions:

37 + 31593647 = 31593684
41 + 31593643 = 31593684
43 + 31593641 = 31593684
53 + 31593631 = 31593684
71 + 31593613 = 31593684
113 + 31593571 = 31593684
131 + 31593553 = 31593684
151 + 31593533 = 31593684

Showing the first eight; more decompositions exist.
