Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478908, here are decompositions:

7 + 478901 = 478908
11 + 478897 = 478908
29 + 478879 = 478908
37 + 478871 = 478908
47 + 478861 = 478908
97 + 478811 = 478908
107 + 478801 = 478908
139 + 478769 = 478908

Showing the first eight; more decompositions exist.
