Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689782, here are decompositions:

5 + 8689777 = 8689782
29 + 8689753 = 8689782
53 + 8689729 = 8689782
71 + 8689711 = 8689782
109 + 8689673 = 8689782
139 + 8689643 = 8689782
173 + 8689609 = 8689782
191 + 8689591 = 8689782

Showing the first eight; more decompositions exist.
