Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595202, here are decompositions:

13 + 31595189 = 31595202
29 + 31595173 = 31595202
61 + 31595141 = 31595202
101 + 31595101 = 31595202
139 + 31595063 = 31595202
181 + 31595021 = 31595202
193 + 31595009 = 31595202
211 + 31594991 = 31595202

Showing the first eight; more decompositions exist.
