Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595244, here are decompositions:

7 + 31595237 = 31595244
67 + 31595177 = 31595244
71 + 31595173 = 31595244
103 + 31595141 = 31595244
181 + 31595063 = 31595244
223 + 31595021 = 31595244
257 + 31594987 = 31595244
281 + 31594963 = 31595244

Showing the first eight; more decompositions exist.
