Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691756, here are decompositions:

5 + 8691751 = 8691756
23 + 8691733 = 8691756
67 + 8691689 = 8691756
83 + 8691673 = 8691756
89 + 8691667 = 8691756
103 + 8691653 = 8691756
113 + 8691643 = 8691756
163 + 8691593 = 8691756

Showing the first eight; more decompositions exist.
