Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470164, here are decompositions:

13 + 31470151 = 31470164
67 + 31470097 = 31470164
97 + 31470067 = 31470164
127 + 31470037 = 31470164
151 + 31470013 = 31470164
211 + 31469953 = 31470164
241 + 31469923 = 31470164
307 + 31469857 = 31470164

Showing the first eight; more decompositions exist.
