Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566298, here are decompositions:

11 + 31566287 = 31566298
47 + 31566251 = 31566298
107 + 31566191 = 31566298
131 + 31566167 = 31566298
167 + 31566131 = 31566298
317 + 31565981 = 31566298
887 + 31565411 = 31566298
947 + 31565351 = 31566298

Showing the first eight; more decompositions exist.
