Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598686, here are decompositions:

3 + 31598683 = 31598686
17 + 31598669 = 31598686
149 + 31598537 = 31598686
167 + 31598519 = 31598686
173 + 31598513 = 31598686
227 + 31598459 = 31598686
263 + 31598423 = 31598686
269 + 31598417 = 31598686

Showing the first eight; more decompositions exist.
