Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467918, here are decompositions:

7 + 31467911 = 31467918
19 + 31467899 = 31467918
71 + 31467847 = 31467918
89 + 31467829 = 31467918
107 + 31467811 = 31467918
109 + 31467809 = 31467918
151 + 31467767 = 31467918
191 + 31467727 = 31467918

Showing the first eight; more decompositions exist.
