Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593916, here are decompositions:

47 + 31593869 = 31593916
83 + 31593833 = 31593916
149 + 31593767 = 31593916
197 + 31593719 = 31593916
227 + 31593689 = 31593916
269 + 31593647 = 31593916
353 + 31593563 = 31593916
383 + 31593533 = 31593916

Showing the first eight; more decompositions exist.
