Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463214, here are decompositions:

11 + 31463203 = 31463214
17 + 31463197 = 31463214
47 + 31463167 = 31463214
53 + 31463161 = 31463214
67 + 31463147 = 31463214
127 + 31463087 = 31463214
131 + 31463083 = 31463214
137 + 31463077 = 31463214

Showing the first eight; more decompositions exist.
