Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123288, here are decompositions:

19 + 123269 = 123288
29 + 123259 = 123288
59 + 123229 = 123288
71 + 123217 = 123288
79 + 123209 = 123288
97 + 123191 = 123288
167 + 123121 = 123288
197 + 123091 = 123288

Showing the first eight; more decompositions exist.
