Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478436, here are decompositions:

3 + 478433 = 478436
19 + 478417 = 478436
37 + 478399 = 478436
97 + 478339 = 478436
163 + 478273 = 478436
193 + 478243 = 478436
223 + 478213 = 478436
229 + 478207 = 478436

Showing the first eight; more decompositions exist.
