Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595010, here are decompositions:

11 + 31594999 = 31595010
19 + 31594991 = 31595010
23 + 31594987 = 31595010
47 + 31594963 = 31595010
79 + 31594931 = 31595010
103 + 31594907 = 31595010
107 + 31594903 = 31595010
127 + 31594883 = 31595010

Showing the first eight; more decompositions exist.
