Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28950, here are decompositions:

17 + 28933 = 28950
23 + 28927 = 28950
29 + 28921 = 28950
41 + 28909 = 28950
71 + 28879 = 28950
79 + 28871 = 28950
83 + 28867 = 28950
107 + 28843 = 28950

Showing the first eight; more decompositions exist.
