Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475438, here are decompositions:

11 + 475427 = 475438
17 + 475421 = 475438
59 + 475379 = 475438
71 + 475367 = 475438
107 + 475331 = 475438
137 + 475301 = 475438
149 + 475289 = 475438
167 + 475271 = 475438

Showing the first eight; more decompositions exist.
