Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596588, here are decompositions:

5 + 31596583 = 31596588
17 + 31596571 = 31596588
47 + 31596541 = 31596588
151 + 31596437 = 31596588
197 + 31596391 = 31596588
271 + 31596317 = 31596588
277 + 31596311 = 31596588
281 + 31596307 = 31596588

Showing the first eight; more decompositions exist.
