Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630678, here are decompositions:

31 + 8630647 = 8630678
37 + 8630641 = 8630678
79 + 8630599 = 8630678
229 + 8630449 = 8630678
367 + 8630311 = 8630678
409 + 8630269 = 8630678
439 + 8630239 = 8630678
487 + 8630191 = 8630678

Showing the first eight; more decompositions exist.
