Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470966, here are decompositions:

13 + 31470953 = 31470966
53 + 31470913 = 31470966
97 + 31470869 = 31470966
103 + 31470863 = 31470966
113 + 31470853 = 31470966
139 + 31470827 = 31470966
167 + 31470799 = 31470966
173 + 31470793 = 31470966

Showing the first eight; more decompositions exist.
