Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28124, here are decompositions:

13 + 28111 = 28124
37 + 28087 = 28124
43 + 28081 = 28124
67 + 28057 = 28124
73 + 28051 = 28124
97 + 28027 = 28124
127 + 27997 = 28124
157 + 27967 = 28124

Showing the first eight; more decompositions exist.
