Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123432, here are decompositions:

5 + 123427 = 123432
13 + 123419 = 123432
31 + 123401 = 123432
53 + 123379 = 123432
59 + 123373 = 123432
109 + 123323 = 123432
163 + 123269 = 123432
173 + 123259 = 123432

Showing the first eight; more decompositions exist.
