Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28104, here are decompositions:

5 + 28099 = 28104
7 + 28097 = 28104
17 + 28087 = 28104
23 + 28081 = 28104
47 + 28057 = 28104
53 + 28051 = 28104
73 + 28031 = 28104
103 + 28001 = 28104

Showing the first eight; more decompositions exist.
