Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646678, here are decompositions:

11 + 8646667 = 8646678
71 + 8646607 = 8646678
97 + 8646581 = 8646678
107 + 8646571 = 8646678
149 + 8646529 = 8646678
167 + 8646511 = 8646678
181 + 8646497 = 8646678
191 + 8646487 = 8646678

Showing the first eight; more decompositions exist.
