Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470438, here are decompositions:

79 + 470359 = 470438
139 + 470299 = 470438
211 + 470227 = 470438
229 + 470209 = 470438
271 + 470167 = 470438
277 + 470161 = 470438
307 + 470131 = 470438
349 + 470089 = 470438

Showing the first eight; more decompositions exist.
