Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123458, here are decompositions:

19 + 123439 = 123458
31 + 123427 = 123458
61 + 123397 = 123458
79 + 123379 = 123458
151 + 123307 = 123458
199 + 123259 = 123458
229 + 123229 = 123458
241 + 123217 = 123458

Showing the first eight; more decompositions exist.
