Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478408, here are decompositions:

5 + 478403 = 478408
17 + 478391 = 478408
137 + 478271 = 478408
149 + 478259 = 478408
167 + 478241 = 478408
239 + 478169 = 478408
251 + 478157 = 478408
269 + 478139 = 478408

Showing the first eight; more decompositions exist.
