Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470388, here are decompositions:

29 + 470359 = 470388
41 + 470347 = 470388
71 + 470317 = 470388
89 + 470299 = 470388
109 + 470279 = 470388
137 + 470251 = 470388
179 + 470209 = 470388
181 + 470207 = 470388

Showing the first eight; more decompositions exist.
