Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463384, here are decompositions:

31 + 31463353 = 31463384
67 + 31463317 = 31463384
103 + 31463281 = 31463384
157 + 31463227 = 31463384
181 + 31463203 = 31463384
223 + 31463161 = 31463384
307 + 31463077 = 31463384
487 + 31462897 = 31463384

Showing the first eight; more decompositions exist.
