Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479986, here are decompositions:

29 + 479957 = 479986
47 + 479939 = 479986
83 + 479903 = 479986
107 + 479879 = 479986
173 + 479813 = 479986
233 + 479753 = 479986
347 + 479639 = 479986
443 + 479543 = 479986

Showing the first eight; more decompositions exist.
