Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475218, here are decompositions:

11 + 475207 = 475218
59 + 475159 = 475218
67 + 475151 = 475218
71 + 475147 = 475218
109 + 475109 = 475218
127 + 475091 = 475218
137 + 475081 = 475218
167 + 475051 = 475218

Showing the first eight; more decompositions exist.
