Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593548, here are decompositions:

31 + 31593517 = 31593548
37 + 31593511 = 31593548
157 + 31593391 = 31593548
241 + 31593307 = 31593548
439 + 31593109 = 31593548
577 + 31592971 = 31593548
601 + 31592947 = 31593548
739 + 31592809 = 31593548

Showing the first eight; more decompositions exist.
