Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593824, here are decompositions:

37 + 31593787 = 31593824
61 + 31593763 = 31593824
103 + 31593721 = 31593824
181 + 31593643 = 31593824
193 + 31593631 = 31593824
211 + 31593613 = 31593824
271 + 31593553 = 31593824
307 + 31593517 = 31593824

Showing the first eight; more decompositions exist.
