Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593598, here are decompositions:

107 + 31593491 = 31593598
137 + 31593461 = 31593598
347 + 31593251 = 31593598
401 + 31593197 = 31593598
587 + 31593011 = 31593598
677 + 31592921 = 31593598
947 + 31592651 = 31593598
977 + 31592621 = 31593598

Showing the first eight; more decompositions exist.
