Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475478, here are decompositions:

37 + 475441 = 475478
61 + 475417 = 475478
97 + 475381 = 475478
109 + 475369 = 475478
127 + 475351 = 475478
151 + 475327 = 475478
181 + 475297 = 475478
271 + 475207 = 475478

Showing the first eight; more decompositions exist.
