Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28958, here are decompositions:

31 + 28927 = 28958
37 + 28921 = 28958
79 + 28879 = 28958
151 + 28807 = 28958
199 + 28759 = 28958
229 + 28729 = 28958
271 + 28687 = 28958
331 + 28627 = 28958

Showing the first eight; more decompositions exist.
