Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478418, here are decompositions:

7 + 478411 = 478418
19 + 478399 = 478418
67 + 478351 = 478418
79 + 478339 = 478418
97 + 478321 = 478418
211 + 478207 = 478418
229 + 478189 = 478418
307 + 478111 = 478418

Showing the first eight; more decompositions exist.
