Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595644, here are decompositions:

71 + 31595573 = 31595644
251 + 31595393 = 31595644
257 + 31595387 = 31595644
281 + 31595363 = 31595644
401 + 31595243 = 31595644
467 + 31595177 = 31595644
503 + 31595141 = 31595644
653 + 31594991 = 31595644

Showing the first eight; more decompositions exist.
