Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567164, here are decompositions:

7 + 31567157 = 31567164
11 + 31567153 = 31567164
73 + 31567091 = 31567164
191 + 31566973 = 31567164
197 + 31566967 = 31567164
263 + 31566901 = 31567164
337 + 31566827 = 31567164
347 + 31566817 = 31567164

Showing the first eight; more decompositions exist.
