Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464012, here are decompositions:

11 + 31464001 = 31464012
53 + 31463959 = 31464012
71 + 31463941 = 31464012
101 + 31463911 = 31464012
103 + 31463909 = 31464012
163 + 31463849 = 31464012
233 + 31463779 = 31464012
269 + 31463743 = 31464012

Showing the first eight; more decompositions exist.
