Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593994, here are decompositions:

11 + 31593983 = 31593994
41 + 31593953 = 31593994
197 + 31593797 = 31593994
227 + 31593767 = 31593994
347 + 31593647 = 31593994
353 + 31593641 = 31593994
431 + 31593563 = 31593994
461 + 31593533 = 31593994

Showing the first eight; more decompositions exist.
