Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478866, here are decompositions:

5 + 478861 = 478866
13 + 478853 = 478866
23 + 478843 = 478866
43 + 478823 = 478866
53 + 478813 = 478866
79 + 478787 = 478866
97 + 478769 = 478866
103 + 478763 = 478866

Showing the first eight; more decompositions exist.
