Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595196, here are decompositions:

7 + 31595189 = 31595196
19 + 31595177 = 31595196
23 + 31595173 = 31595196
137 + 31595059 = 31595196
197 + 31594999 = 31595196
233 + 31594963 = 31595196
277 + 31594919 = 31595196
293 + 31594903 = 31595196

Showing the first eight; more decompositions exist.
