Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470006, here are decompositions:

17 + 31469989 = 31470006
19 + 31469987 = 31470006
53 + 31469953 = 31470006
83 + 31469923 = 31470006
103 + 31469903 = 31470006
149 + 31469857 = 31470006
157 + 31469849 = 31470006
193 + 31469813 = 31470006

Showing the first eight; more decompositions exist.
