Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593238, here are decompositions:

41 + 31593197 = 31593238
191 + 31593047 = 31593238
227 + 31593011 = 31593238
317 + 31592921 = 31593238
389 + 31592849 = 31593238
491 + 31592747 = 31593238
587 + 31592651 = 31593238
617 + 31592621 = 31593238

Showing the first eight; more decompositions exist.
