Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598568, here are decompositions:

31 + 31598537 = 31598568
47 + 31598521 = 31598568
109 + 31598459 = 31598568
149 + 31598419 = 31598568
151 + 31598417 = 31598568
167 + 31598401 = 31598568
191 + 31598377 = 31598568
241 + 31598327 = 31598568

Showing the first eight; more decompositions exist.
