Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469970, here are decompositions:

17 + 31469953 = 31469970
47 + 31469923 = 31469970
67 + 31469903 = 31469970
109 + 31469861 = 31469970
113 + 31469857 = 31469970
157 + 31469813 = 31469970
173 + 31469797 = 31469970
229 + 31469741 = 31469970

Showing the first eight; more decompositions exist.
