Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595224, here are decompositions:

5 + 31595219 = 31595224
47 + 31595177 = 31595224
83 + 31595141 = 31595224
233 + 31594991 = 31595224
263 + 31594961 = 31595224
293 + 31594931 = 31595224
317 + 31594907 = 31595224
347 + 31594877 = 31595224

Showing the first eight; more decompositions exist.
