Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593958, here are decompositions:

5 + 31593953 = 31593958
89 + 31593869 = 31593958
191 + 31593767 = 31593958
239 + 31593719 = 31593958
269 + 31593689 = 31593958
311 + 31593647 = 31593958
317 + 31593641 = 31593958
467 + 31593491 = 31593958

Showing the first eight; more decompositions exist.
