Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593798, here are decompositions:

11 + 31593787 = 31593798
31 + 31593767 = 31593798
79 + 31593719 = 31593798
109 + 31593689 = 31593798
151 + 31593647 = 31593798
157 + 31593641 = 31593798
167 + 31593631 = 31593798
191 + 31593607 = 31593798

Showing the first eight; more decompositions exist.
