Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568, here are decompositions:

37 + 31531 = 31568
79 + 31489 = 31568
181 + 31387 = 31568
211 + 31357 = 31568
241 + 31327 = 31568
331 + 31237 = 31568
337 + 31231 = 31568
349 + 31219 = 31568

Showing the first eight; more decompositions exist.
