Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28184, here are decompositions:

3 + 28181 = 28184
61 + 28123 = 28184
73 + 28111 = 28184
97 + 28087 = 28184
103 + 28081 = 28184
127 + 28057 = 28184
157 + 28027 = 28184
223 + 27961 = 28184

Showing the first eight; more decompositions exist.
