Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28866, here are decompositions:

7 + 28859 = 28866
23 + 28843 = 28866
29 + 28837 = 28866
53 + 28813 = 28866
59 + 28807 = 28866
73 + 28793 = 28866
107 + 28759 = 28866
113 + 28753 = 28866

Showing the first eight; more decompositions exist.
