Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42438, here are decompositions:

5 + 42433 = 42438
29 + 42409 = 42438
31 + 42407 = 42438
41 + 42397 = 42438
47 + 42391 = 42438
59 + 42379 = 42438
79 + 42359 = 42438
89 + 42349 = 42438

Showing the first eight; more decompositions exist.
