Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596582, here are decompositions:

11 + 31596571 = 31596582
29 + 31596553 = 31596582
41 + 31596541 = 31596582
71 + 31596511 = 31596582
109 + 31596473 = 31596582
163 + 31596419 = 31596582
179 + 31596403 = 31596582
181 + 31596401 = 31596582

Showing the first eight; more decompositions exist.
