Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123272, here are decompositions:

3 + 123269 = 123272
13 + 123259 = 123272
43 + 123229 = 123272
103 + 123169 = 123272
151 + 123121 = 123272
181 + 123091 = 123272
223 + 123049 = 123272
241 + 123031 = 123272

Showing the first eight; more decompositions exist.
