Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42426, here are decompositions:

17 + 42409 = 42426
19 + 42407 = 42426
23 + 42403 = 42426
29 + 42397 = 42426
47 + 42379 = 42426
53 + 42373 = 42426
67 + 42359 = 42426
89 + 42337 = 42426

Showing the first eight; more decompositions exist.
