Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493016, here are decompositions:

7 + 31493009 = 31493016
19 + 31492997 = 31493016
53 + 31492963 = 31493016
73 + 31492943 = 31493016
83 + 31492933 = 31493016
109 + 31492907 = 31493016
157 + 31492859 = 31493016
167 + 31492849 = 31493016

Showing the first eight; more decompositions exist.
