Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595508, here are decompositions:

41 + 31595467 = 31595508
101 + 31595407 = 31595508
137 + 31595371 = 31595508
229 + 31595279 = 31595508
257 + 31595251 = 31595508
271 + 31595237 = 31595508
331 + 31595177 = 31595508
367 + 31595141 = 31595508

Showing the first eight; more decompositions exist.
