Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475220, here are decompositions:

13 + 475207 = 475220
61 + 475159 = 475220
73 + 475147 = 475220
79 + 475141 = 475220
127 + 475093 = 475220
139 + 475081 = 475220
271 + 474949 = 475220
283 + 474937 = 475220

Showing the first eight; more decompositions exist.
