Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478574, here are decompositions:

3 + 478571 = 478574
43 + 478531 = 478574
157 + 478417 = 478574
163 + 478411 = 478574
223 + 478351 = 478574
331 + 478243 = 478574
367 + 478207 = 478574
463 + 478111 = 478574

Showing the first eight; more decompositions exist.
