Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595074, here are decompositions:

11 + 31595063 = 31595074
53 + 31595021 = 31595074
83 + 31594991 = 31595074
113 + 31594961 = 31595074
167 + 31594907 = 31595074
191 + 31594883 = 31595074
197 + 31594877 = 31595074
263 + 31594811 = 31595074

Showing the first eight; more decompositions exist.
