Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593066, here are decompositions:

19 + 31593047 = 31593066
73 + 31592993 = 31593066
83 + 31592983 = 31593066
107 + 31592959 = 31593066
223 + 31592843 = 31593066
233 + 31592833 = 31593066
257 + 31592809 = 31593066
269 + 31592797 = 31593066

Showing the first eight; more decompositions exist.
