Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42428, here are decompositions:

19 + 42409 = 42428
31 + 42397 = 42428
37 + 42391 = 42428
79 + 42349 = 42428
97 + 42331 = 42428
241 + 42187 = 42428
271 + 42157 = 42428
367 + 42061 = 42428

Showing the first eight; more decompositions exist.
