Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478666, here are decompositions:

29 + 478637 = 478666
173 + 478493 = 478666
233 + 478433 = 478666
239 + 478427 = 478666
263 + 478403 = 478666
467 + 478199 = 478666
509 + 478157 = 478666
599 + 478067 = 478666

Showing the first eight; more decompositions exist.
