Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593594, here are decompositions:

5 + 31593589 = 31593594
23 + 31593571 = 31593594
31 + 31593563 = 31593594
41 + 31593553 = 31593594
61 + 31593533 = 31593594
83 + 31593511 = 31593594
103 + 31593491 = 31593594
157 + 31593437 = 31593594

Showing the first eight; more decompositions exist.
