Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478420, here are decompositions:

3 + 478417 = 478420
17 + 478403 = 478420
29 + 478391 = 478420
149 + 478271 = 478420
167 + 478253 = 478420
179 + 478241 = 478420
251 + 478169 = 478420
263 + 478157 = 478420

Showing the first eight; more decompositions exist.
