Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598608, here are decompositions:

17 + 31598591 = 31598608
71 + 31598537 = 31598608
89 + 31598519 = 31598608
149 + 31598459 = 31598608
191 + 31598417 = 31598608
227 + 31598381 = 31598608
281 + 31598327 = 31598608
347 + 31598261 = 31598608

Showing the first eight; more decompositions exist.
