Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493014, here are decompositions:

5 + 31493009 = 31493014
17 + 31492997 = 31493014
23 + 31492991 = 31493014
71 + 31492943 = 31493014
107 + 31492907 = 31493014
167 + 31492847 = 31493014
173 + 31492841 = 31493014
233 + 31492781 = 31493014

Showing the first eight; more decompositions exist.
