Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593982, here are decompositions:

23 + 31593959 = 31593982
29 + 31593953 = 31593982
113 + 31593869 = 31593982
149 + 31593833 = 31593982
263 + 31593719 = 31593982
293 + 31593689 = 31593982
353 + 31593629 = 31593982
419 + 31593563 = 31593982

Showing the first eight; more decompositions exist.
