Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64678, here are decompositions:

11 + 64667 = 64678
17 + 64661 = 64678
101 + 64577 = 64678
179 + 64499 = 64678
227 + 64451 = 64678
239 + 64439 = 64678
359 + 64319 = 64678
461 + 64217 = 64678

Showing the first eight; more decompositions exist.
