Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470012, here are decompositions:

23 + 31469989 = 31470012
59 + 31469953 = 31470012
89 + 31469923 = 31470012
109 + 31469903 = 31470012
151 + 31469861 = 31470012
163 + 31469849 = 31470012
199 + 31469813 = 31470012
229 + 31469783 = 31470012

Showing the first eight; more decompositions exist.
