Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588416, here are decompositions:

17 + 31588399 = 31588416
47 + 31588369 = 31588416
59 + 31588357 = 31588416
103 + 31588313 = 31588416
109 + 31588307 = 31588416
113 + 31588303 = 31588416
149 + 31588267 = 31588416
163 + 31588253 = 31588416

Showing the first eight; more decompositions exist.
