Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689764, here are decompositions:

11 + 8689753 = 8689764
37 + 8689727 = 8689764
53 + 8689711 = 8689764
103 + 8689661 = 8689764
107 + 8689657 = 8689764
137 + 8689627 = 8689764
173 + 8689591 = 8689764
191 + 8689573 = 8689764

Showing the first eight; more decompositions exist.
