Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475290, here are decompositions:

7 + 475283 = 475290
17 + 475273 = 475290
19 + 475271 = 475290
47 + 475243 = 475290
61 + 475229 = 475290
71 + 475219 = 475290
83 + 475207 = 475290
131 + 475159 = 475290

Showing the first eight; more decompositions exist.
