Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593228, here are decompositions:

31 + 31593197 = 31593228
131 + 31593097 = 31593228
181 + 31593047 = 31593228
197 + 31593031 = 31593228
257 + 31592971 = 31593228
269 + 31592959 = 31593228
281 + 31592947 = 31593228
307 + 31592921 = 31593228

Showing the first eight; more decompositions exist.
