Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478434, here are decompositions:

7 + 478427 = 478434
13 + 478421 = 478434
17 + 478417 = 478434
23 + 478411 = 478434
31 + 478403 = 478434
43 + 478391 = 478434
83 + 478351 = 478434
113 + 478321 = 478434

Showing the first eight; more decompositions exist.
