Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464154, here are decompositions:

5 + 31464149 = 31464154
11 + 31464143 = 31464154
17 + 31464137 = 31464154
107 + 31464047 = 31464154
191 + 31463963 = 31464154
233 + 31463921 = 31464154
257 + 31463897 = 31464154
263 + 31463891 = 31464154

Showing the first eight; more decompositions exist.
