Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598664, here are decompositions:

17 + 31598647 = 31598664
73 + 31598591 = 31598664
127 + 31598537 = 31598664
151 + 31598513 = 31598664
241 + 31598423 = 31598664
263 + 31598401 = 31598664
283 + 31598381 = 31598664
311 + 31598353 = 31598664

Showing the first eight; more decompositions exist.
