Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593826, here are decompositions:

29 + 31593797 = 31593826
59 + 31593767 = 31593826
107 + 31593719 = 31593826
137 + 31593689 = 31593826
179 + 31593647 = 31593826
197 + 31593629 = 31593826
263 + 31593563 = 31593826
293 + 31593533 = 31593826

Showing the first eight; more decompositions exist.
