Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596528, here are decompositions:

17 + 31596511 = 31596528
31 + 31596497 = 31596528
109 + 31596419 = 31596528
127 + 31596401 = 31596528
137 + 31596391 = 31596528
149 + 31596379 = 31596528
211 + 31596317 = 31596528
401 + 31596127 = 31596528

Showing the first eight; more decompositions exist.
