Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593564, here are decompositions:

11 + 31593553 = 31593564
31 + 31593533 = 31593564
47 + 31593517 = 31593564
53 + 31593511 = 31593564
61 + 31593503 = 31593564
73 + 31593491 = 31593564
103 + 31593461 = 31593564
127 + 31593437 = 31593564

Showing the first eight; more decompositions exist.
