Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478426, here are decompositions:

5 + 478421 = 478426
23 + 478403 = 478426
83 + 478343 = 478426
167 + 478259 = 478426
173 + 478253 = 478426
227 + 478199 = 478426
257 + 478169 = 478426
269 + 478157 = 478426

Showing the first eight; more decompositions exist.
