Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595154, here are decompositions:

13 + 31595141 = 31595154
53 + 31595101 = 31595154
163 + 31594991 = 31595154
167 + 31594987 = 31595154
191 + 31594963 = 31595154
193 + 31594961 = 31595154
223 + 31594931 = 31595154
251 + 31594903 = 31595154

Showing the first eight; more decompositions exist.
