Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595496, here are decompositions:

13 + 31595483 = 31595496
29 + 31595467 = 31595496
89 + 31595407 = 31595496
103 + 31595393 = 31595496
109 + 31595387 = 31595496
113 + 31595383 = 31595496
223 + 31595273 = 31595496
277 + 31595219 = 31595496

Showing the first eight; more decompositions exist.
