Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23028, here are decompositions:

7 + 23021 = 23028
11 + 23017 = 23028
17 + 23011 = 23028
67 + 22961 = 23028
107 + 22921 = 23028
127 + 22901 = 23028
151 + 22877 = 23028
157 + 22871 = 23028

Showing the first eight; more decompositions exist.
