Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464214, here are decompositions:

71 + 31464143 = 31464214
167 + 31464047 = 31464214
251 + 31463963 = 31464214
293 + 31463921 = 31464214
317 + 31463897 = 31464214
827 + 31463387 = 31464214
953 + 31463261 = 31464214
1091 + 31463123 = 31464214

Showing the first eight; more decompositions exist.
