Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28208, here are decompositions:

7 + 28201 = 28208
97 + 28111 = 28208
109 + 28099 = 28208
127 + 28081 = 28208
139 + 28069 = 28208
151 + 28057 = 28208
157 + 28051 = 28208
181 + 28027 = 28208

Showing the first eight; more decompositions exist.
