Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478806, here are decompositions:

5 + 478801 = 478806
19 + 478787 = 478806
37 + 478769 = 478806
43 + 478763 = 478806
59 + 478747 = 478806
67 + 478739 = 478806
79 + 478727 = 478806
109 + 478697 = 478806

Showing the first eight; more decompositions exist.
