Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479280, here are decompositions:

13 + 479267 = 479280
17 + 479263 = 479280
37 + 479243 = 479280
41 + 479239 = 479280
59 + 479221 = 479280
71 + 479209 = 479280
79 + 479201 = 479280
89 + 479191 = 479280

Showing the first eight; more decompositions exist.
