Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593048, here are decompositions:

17 + 31593031 = 31593048
37 + 31593011 = 31593048
89 + 31592959 = 31593048
101 + 31592947 = 31593048
127 + 31592921 = 31593048
199 + 31592849 = 31593048
239 + 31592809 = 31593048
251 + 31592797 = 31593048

Showing the first eight; more decompositions exist.
