Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464164, here are decompositions:

97 + 31464067 = 31464164
103 + 31464061 = 31464164
163 + 31464001 = 31464164
223 + 31463941 = 31464164
271 + 31463893 = 31464164
307 + 31463857 = 31464164
337 + 31463827 = 31464164
367 + 31463797 = 31464164

Showing the first eight; more decompositions exist.
