Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478298, here are decompositions:

109 + 478189 = 478298
127 + 478171 = 478298
199 + 478099 = 478298
211 + 478087 = 478298
229 + 478069 = 478298
307 + 477991 = 478298
487 + 477811 = 478298
571 + 477727 = 478298

Showing the first eight; more decompositions exist.
