Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670678, here are decompositions:

11 + 8670667 = 8670678
41 + 8670637 = 8670678
59 + 8670619 = 8670678
67 + 8670611 = 8670678
89 + 8670589 = 8670678
127 + 8670551 = 8670678
179 + 8670499 = 8670678
197 + 8670481 = 8670678

Showing the first eight; more decompositions exist.
