Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2588, here are decompositions:

31 + 2557 = 2588
37 + 2551 = 2588
67 + 2521 = 2588
151 + 2437 = 2588
199 + 2389 = 2588
211 + 2377 = 2588
241 + 2347 = 2588
277 + 2311 = 2588

Showing the first eight; more decompositions exist.
