Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479920, here are decompositions:

11 + 479909 = 479920
17 + 479903 = 479920
29 + 479891 = 479920
41 + 479879 = 479920
59 + 479861 = 479920
107 + 479813 = 479920
137 + 479783 = 479920
149 + 479771 = 479920

Showing the first eight; more decompositions exist.
