Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42456, here are decompositions:

5 + 42451 = 42456
13 + 42443 = 42456
19 + 42437 = 42456
23 + 42433 = 42456
47 + 42409 = 42456
53 + 42403 = 42456
59 + 42397 = 42456
83 + 42373 = 42456

Showing the first eight; more decompositions exist.
