Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464008, here are decompositions:

7 + 31464001 = 31464008
67 + 31463941 = 31464008
97 + 31463911 = 31464008
151 + 31463857 = 31464008
181 + 31463827 = 31464008
211 + 31463797 = 31464008
229 + 31463779 = 31464008
241 + 31463767 = 31464008

Showing the first eight; more decompositions exist.
