Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478986, here are decompositions:

19 + 478967 = 478986
23 + 478963 = 478986
43 + 478943 = 478986
59 + 478927 = 478986
73 + 478913 = 478986
89 + 478897 = 478986
107 + 478879 = 478986
163 + 478823 = 478986

Showing the first eight; more decompositions exist.
