Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595184, here are decompositions:

7 + 31595177 = 31595184
11 + 31595173 = 31595184
43 + 31595141 = 31595184
83 + 31595101 = 31595184
163 + 31595021 = 31595184
193 + 31594991 = 31595184
197 + 31594987 = 31595184
223 + 31594961 = 31595184

Showing the first eight; more decompositions exist.
