Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669678, here are decompositions:

7 + 8669671 = 8669678
67 + 8669611 = 8669678
151 + 8669527 = 8669678
337 + 8669341 = 8669678
349 + 8669329 = 8669678
439 + 8669239 = 8669678
499 + 8669179 = 8669678
571 + 8669107 = 8669678

Showing the first eight; more decompositions exist.
