Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493022, here are decompositions:

5 + 31493017 = 31493022
13 + 31493009 = 31493022
31 + 31492991 = 31493022
59 + 31492963 = 31493022
79 + 31492943 = 31493022
89 + 31492933 = 31493022
101 + 31492921 = 31493022
163 + 31492859 = 31493022

Showing the first eight; more decompositions exist.
