Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588, here are decompositions:

5 + 31583 = 31588
41 + 31547 = 31588
47 + 31541 = 31588
71 + 31517 = 31588
107 + 31481 = 31588
191 + 31397 = 31588
197 + 31391 = 31588
251 + 31337 = 31588

Showing the first eight; more decompositions exist.
