Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467916, here are decompositions:

5 + 31467911 = 31467916
17 + 31467899 = 31467916
23 + 31467893 = 31467916
107 + 31467809 = 31467916
149 + 31467767 = 31467916
197 + 31467719 = 31467916
239 + 31467677 = 31467916
269 + 31467647 = 31467916

Showing the first eight; more decompositions exist.
