Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593838, here are decompositions:

5 + 31593833 = 31593838
41 + 31593797 = 31593838
71 + 31593767 = 31593838
149 + 31593689 = 31593838
191 + 31593647 = 31593838
197 + 31593641 = 31593838
347 + 31593491 = 31593838
359 + 31593479 = 31593838

Showing the first eight; more decompositions exist.
