Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478340, here are decompositions:

19 + 478321 = 478340
67 + 478273 = 478340
97 + 478243 = 478340
127 + 478213 = 478340
151 + 478189 = 478340
211 + 478129 = 478340
229 + 478111 = 478340
241 + 478099 = 478340

Showing the first eight; more decompositions exist.
