Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28910, here are decompositions:

31 + 28879 = 28910
43 + 28867 = 28910
67 + 28843 = 28910
73 + 28837 = 28910
97 + 28813 = 28910
103 + 28807 = 28910
139 + 28771 = 28910
151 + 28759 = 28910

Showing the first eight; more decompositions exist.
