Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691896, here are decompositions:

7 + 8691889 = 8691896
13 + 8691883 = 8691896
43 + 8691853 = 8691896
97 + 8691799 = 8691896
163 + 8691733 = 8691896
223 + 8691673 = 8691896
229 + 8691667 = 8691896
307 + 8691589 = 8691896

Showing the first eight; more decompositions exist.
