Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593600, here are decompositions:

11 + 31593589 = 31593600
29 + 31593571 = 31593600
37 + 31593563 = 31593600
47 + 31593553 = 31593600
67 + 31593533 = 31593600
83 + 31593517 = 31593600
89 + 31593511 = 31593600
97 + 31593503 = 31593600

Showing the first eight; more decompositions exist.
