Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463480, here are decompositions:

3 + 31463477 = 31463480
73 + 31463407 = 31463480
127 + 31463353 = 31463480
151 + 31463329 = 31463480
163 + 31463317 = 31463480
199 + 31463281 = 31463480
211 + 31463269 = 31463480
277 + 31463203 = 31463480

Showing the first eight; more decompositions exist.
