Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478664, here are decompositions:

13 + 478651 = 478664
37 + 478627 = 478664
61 + 478603 = 478664
181 + 478483 = 478664
211 + 478453 = 478664
223 + 478441 = 478664
313 + 478351 = 478664
421 + 478243 = 478664

Showing the first eight; more decompositions exist.
