Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478654, here are decompositions:

3 + 478651 = 478654
17 + 478637 = 478654
23 + 478631 = 478654
83 + 478571 = 478654
131 + 478523 = 478654
173 + 478481 = 478654
227 + 478427 = 478654
233 + 478421 = 478654

Showing the first eight; more decompositions exist.
