Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598670, here are decompositions:

23 + 31598647 = 31598670
79 + 31598591 = 31598670
127 + 31598543 = 31598670
149 + 31598521 = 31598670
151 + 31598519 = 31598670
157 + 31598513 = 31598670
211 + 31598459 = 31598670
251 + 31598419 = 31598670

Showing the first eight; more decompositions exist.
