Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12438, here are decompositions:

5 + 12433 = 12438
17 + 12421 = 12438
29 + 12409 = 12438
37 + 12401 = 12438
47 + 12391 = 12438
59 + 12379 = 12438
61 + 12377 = 12438
109 + 12329 = 12438

Showing the first eight; more decompositions exist.
