Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478658, here are decompositions:

7 + 478651 = 478658
31 + 478627 = 478658
79 + 478579 = 478658
127 + 478531 = 478658
199 + 478459 = 478658
241 + 478417 = 478658
307 + 478351 = 478658
337 + 478321 = 478658

Showing the first eight; more decompositions exist.
