Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470188, here are decompositions:

101 + 470087 = 470188
107 + 470081 = 470188
149 + 470039 = 470188
167 + 470021 = 470188
269 + 469919 = 470188
281 + 469907 = 470188
311 + 469877 = 470188
347 + 469841 = 470188

Showing the first eight; more decompositions exist.
