Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463540, here are decompositions:

7 + 31463533 = 31463540
13 + 31463527 = 31463540
151 + 31463389 = 31463540
211 + 31463329 = 31463540
223 + 31463317 = 31463540
271 + 31463269 = 31463540
313 + 31463227 = 31463540
337 + 31463203 = 31463540

Showing the first eight; more decompositions exist.
