Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470806, here are decompositions:

23 + 470783 = 470806
137 + 470669 = 470806
179 + 470627 = 470806
197 + 470609 = 470806
227 + 470579 = 470806
293 + 470513 = 470806
317 + 470489 = 470806
353 + 470453 = 470806

Showing the first eight; more decompositions exist.
