Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598, here are decompositions:

31 + 31567 = 31598
67 + 31531 = 31598
109 + 31489 = 31598
211 + 31387 = 31598
241 + 31357 = 31598
271 + 31327 = 31598
277 + 31321 = 31598
331 + 31267 = 31598

Showing the first eight; more decompositions exist.
