Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598658, here are decompositions:

11 + 31598647 = 31598658
67 + 31598591 = 31598658
137 + 31598521 = 31598658
139 + 31598519 = 31598658
199 + 31598459 = 31598658
239 + 31598419 = 31598658
241 + 31598417 = 31598658
257 + 31598401 = 31598658

Showing the first eight; more decompositions exist.
