Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123438, here are decompositions:

5 + 123433 = 123438
11 + 123427 = 123438
19 + 123419 = 123438
31 + 123407 = 123438
37 + 123401 = 123438
41 + 123397 = 123438
59 + 123379 = 123438
61 + 123377 = 123438

Showing the first eight; more decompositions exist.
