Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478466, here are decompositions:

7 + 478459 = 478466
13 + 478453 = 478466
67 + 478399 = 478466
127 + 478339 = 478466
193 + 478273 = 478466
223 + 478243 = 478466
277 + 478189 = 478466
337 + 478129 = 478466

Showing the first eight; more decompositions exist.
