Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28110, here are decompositions:

11 + 28099 = 28110
13 + 28097 = 28110
23 + 28087 = 28110
29 + 28081 = 28110
41 + 28069 = 28110
53 + 28057 = 28110
59 + 28051 = 28110
79 + 28031 = 28110

Showing the first eight; more decompositions exist.
