Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594150, here are decompositions:

17 + 31594133 = 31594150
53 + 31594097 = 31594150
89 + 31594061 = 31594150
101 + 31594049 = 31594150
167 + 31593983 = 31594150
191 + 31593959 = 31594150
197 + 31593953 = 31594150
281 + 31593869 = 31594150

Showing the first eight; more decompositions exist.
