Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478836, here are decompositions:

5 + 478831 = 478836
13 + 478823 = 478836
23 + 478813 = 478836
67 + 478769 = 478836
73 + 478763 = 478836
89 + 478747 = 478836
97 + 478739 = 478836
107 + 478729 = 478836

Showing the first eight; more decompositions exist.
