Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463348, here are decompositions:

19 + 31463329 = 31463348
31 + 31463317 = 31463348
67 + 31463281 = 31463348
79 + 31463269 = 31463348
151 + 31463197 = 31463348
181 + 31463167 = 31463348
211 + 31463137 = 31463348
271 + 31463077 = 31463348

Showing the first eight; more decompositions exist.
