Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595016, here are decompositions:

7 + 31595009 = 31595016
17 + 31594999 = 31595016
29 + 31594987 = 31595016
53 + 31594963 = 31595016
97 + 31594919 = 31595016
109 + 31594907 = 31595016
113 + 31594903 = 31595016
139 + 31594877 = 31595016

Showing the first eight; more decompositions exist.
