Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464118, here are decompositions:

71 + 31464047 = 31464118
197 + 31463921 = 31464118
227 + 31463891 = 31464118
239 + 31463879 = 31464118
269 + 31463849 = 31464118
311 + 31463807 = 31464118
359 + 31463759 = 31464118
401 + 31463717 = 31464118

Showing the first eight; more decompositions exist.
