Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566954, here are decompositions:

43 + 31566911 = 31566954
53 + 31566901 = 31566954
127 + 31566827 = 31566954
137 + 31566817 = 31566954
151 + 31566803 = 31566954
157 + 31566797 = 31566954
191 + 31566763 = 31566954
241 + 31566713 = 31566954

Showing the first eight; more decompositions exist.
