Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464256, here are decompositions:

23 + 31464233 = 31464256
107 + 31464149 = 31464256
113 + 31464143 = 31464256
293 + 31463963 = 31464256
347 + 31463909 = 31464256
359 + 31463897 = 31464256
449 + 31463807 = 31464256
773 + 31463483 = 31464256

Showing the first eight; more decompositions exist.
