Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42422, here are decompositions:

13 + 42409 = 42422
19 + 42403 = 42422
31 + 42391 = 42422
43 + 42379 = 42422
73 + 42349 = 42422
139 + 42283 = 42422
199 + 42223 = 42422
229 + 42193 = 42422

Showing the first eight; more decompositions exist.
