Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28926, here are decompositions:

5 + 28921 = 28926
17 + 28909 = 28926
47 + 28879 = 28926
59 + 28867 = 28926
67 + 28859 = 28926
83 + 28843 = 28926
89 + 28837 = 28926
109 + 28817 = 28926

Showing the first eight; more decompositions exist.
