Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478808, here are decompositions:

7 + 478801 = 478808
61 + 478747 = 478808
67 + 478741 = 478808
79 + 478729 = 478808
97 + 478711 = 478808
157 + 478651 = 478808
181 + 478627 = 478808
229 + 478579 = 478808

Showing the first eight; more decompositions exist.
