Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478438, here are decompositions:

5 + 478433 = 478438
11 + 478427 = 478438
17 + 478421 = 478438
47 + 478391 = 478438
167 + 478271 = 478438
179 + 478259 = 478438
197 + 478241 = 478438
239 + 478199 = 478438

Showing the first eight; more decompositions exist.
