Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595392, here are decompositions:

5 + 31595387 = 31595392
29 + 31595363 = 31595392
113 + 31595279 = 31595392
149 + 31595243 = 31595392
173 + 31595219 = 31595392
251 + 31595141 = 31595392
383 + 31595009 = 31595392
401 + 31594991 = 31595392

Showing the first eight; more decompositions exist.
