Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464264, here are decompositions:

31 + 31464233 = 31464264
71 + 31464193 = 31464264
127 + 31464137 = 31464264
197 + 31464067 = 31464264
233 + 31464031 = 31464264
263 + 31464001 = 31464264
353 + 31463911 = 31464264
367 + 31463897 = 31464264

Showing the first eight; more decompositions exist.
