Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593018, here are decompositions:

7 + 31593011 = 31593018
47 + 31592971 = 31593018
59 + 31592959 = 31593018
71 + 31592947 = 31593018
97 + 31592921 = 31593018
239 + 31592779 = 31593018
257 + 31592761 = 31593018
271 + 31592747 = 31593018

Showing the first eight; more decompositions exist.
