Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595190, here are decompositions:

13 + 31595177 = 31595190
17 + 31595173 = 31595190
89 + 31595101 = 31595190
127 + 31595063 = 31595190
131 + 31595059 = 31595190
181 + 31595009 = 31595190
191 + 31594999 = 31595190
199 + 31594991 = 31595190

Showing the first eight; more decompositions exist.
