Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467966, here are decompositions:

17 + 31467949 = 31467966
29 + 31467937 = 31467966
67 + 31467899 = 31467966
73 + 31467893 = 31467966
113 + 31467853 = 31467966
137 + 31467829 = 31467966
157 + 31467809 = 31467966
199 + 31467767 = 31467966

Showing the first eight; more decompositions exist.
