Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691678, here are decompositions:

5 + 8691673 = 8691678
11 + 8691667 = 8691678
89 + 8691589 = 8691678
97 + 8691581 = 8691678
137 + 8691541 = 8691678
181 + 8691497 = 8691678
197 + 8691481 = 8691678
199 + 8691479 = 8691678

Showing the first eight; more decompositions exist.
