Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464148, here are decompositions:

5 + 31464143 = 31464148
11 + 31464137 = 31464148
101 + 31464047 = 31464148
227 + 31463921 = 31464148
239 + 31463909 = 31464148
251 + 31463897 = 31464148
257 + 31463891 = 31464148
269 + 31463879 = 31464148

Showing the first eight; more decompositions exist.
