Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478256, here are decompositions:

3 + 478253 = 478256
13 + 478243 = 478256
43 + 478213 = 478256
67 + 478189 = 478256
127 + 478129 = 478256
157 + 478099 = 478256
193 + 478063 = 478256
283 + 477973 = 478256

Showing the first eight; more decompositions exist.
