Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691786, here are decompositions:

23 + 8691763 = 8691786
53 + 8691733 = 8691786
97 + 8691689 = 8691786
113 + 8691673 = 8691786
163 + 8691623 = 8691786
193 + 8691593 = 8691786
197 + 8691589 = 8691786
199 + 8691587 = 8691786

Showing the first eight; more decompositions exist.
