Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689784, here are decompositions:

7 + 8689777 = 8689784
31 + 8689753 = 8689784
73 + 8689711 = 8689784
97 + 8689687 = 8689784
127 + 8689657 = 8689784
157 + 8689627 = 8689784
193 + 8689591 = 8689784
211 + 8689573 = 8689784

Showing the first eight; more decompositions exist.
