Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479980, here are decompositions:

23 + 479957 = 479980
29 + 479951 = 479980
41 + 479939 = 479980
71 + 479909 = 479980
89 + 479891 = 479980
101 + 479879 = 479980
167 + 479813 = 479980
197 + 479783 = 479980

Showing the first eight; more decompositions exist.
