Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478422, here are decompositions:

5 + 478417 = 478422
11 + 478411 = 478422
19 + 478403 = 478422
23 + 478399 = 478422
31 + 478391 = 478422
71 + 478351 = 478422
79 + 478343 = 478422
83 + 478339 = 478422

Showing the first eight; more decompositions exist.
