Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475490, here are decompositions:

7 + 475483 = 475490
61 + 475429 = 475490
73 + 475417 = 475490
109 + 475381 = 475490
139 + 475351 = 475490
157 + 475333 = 475490
163 + 475327 = 475490
193 + 475297 = 475490

Showing the first eight; more decompositions exist.
