Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56406, here are decompositions:

5 + 56401 = 56406
13 + 56393 = 56406
23 + 56383 = 56406
29 + 56377 = 56406
37 + 56369 = 56406
47 + 56359 = 56406
73 + 56333 = 56406
107 + 56299 = 56406

Showing the first eight; more decompositions exist.
