Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28962, here are decompositions:

13 + 28949 = 28962
29 + 28933 = 28962
41 + 28921 = 28962
53 + 28909 = 28962
61 + 28901 = 28962
83 + 28879 = 28962
103 + 28859 = 28962
149 + 28813 = 28962

Showing the first eight; more decompositions exist.
