Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598682, here are decompositions:

13 + 31598669 = 31598682
139 + 31598543 = 31598682
163 + 31598519 = 31598682
223 + 31598459 = 31598682
233 + 31598449 = 31598682
263 + 31598419 = 31598682
281 + 31598401 = 31598682
383 + 31598299 = 31598682

Showing the first eight; more decompositions exist.
