Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28098, here are decompositions:

11 + 28087 = 28098
17 + 28081 = 28098
29 + 28069 = 28098
41 + 28057 = 28098
47 + 28051 = 28098
67 + 28031 = 28098
71 + 28027 = 28098
79 + 28019 = 28098

Showing the first eight; more decompositions exist.
