Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479988, here are decompositions:

17 + 479971 = 479988
31 + 479957 = 479988
37 + 479951 = 479988
79 + 479909 = 479988
97 + 479891 = 479988
107 + 479881 = 479988
109 + 479879 = 479988
127 + 479861 = 479988

Showing the first eight; more decompositions exist.
