Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478788, here are decompositions:

19 + 478769 = 478788
41 + 478747 = 478788
47 + 478741 = 478788
59 + 478729 = 478788
61 + 478727 = 478788
109 + 478679 = 478788
137 + 478651 = 478788
151 + 478637 = 478788

Showing the first eight; more decompositions exist.
