Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478286, here are decompositions:

13 + 478273 = 478286
43 + 478243 = 478286
73 + 478213 = 478286
79 + 478207 = 478286
97 + 478189 = 478286
157 + 478129 = 478286
199 + 478087 = 478286
223 + 478063 = 478286

Showing the first eight; more decompositions exist.
