Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28134, here are decompositions:

11 + 28123 = 28134
23 + 28111 = 28134
37 + 28097 = 28134
47 + 28087 = 28134
53 + 28081 = 28134
83 + 28051 = 28134
103 + 28031 = 28134
107 + 28027 = 28134

Showing the first eight; more decompositions exist.
