Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595070, here are decompositions:

7 + 31595063 = 31595070
11 + 31595059 = 31595070
61 + 31595009 = 31595070
71 + 31594999 = 31595070
79 + 31594991 = 31595070
83 + 31594987 = 31595070
107 + 31594963 = 31595070
109 + 31594961 = 31595070

Showing the first eight; more decompositions exist.
