Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689766, here are decompositions:

13 + 8689753 = 8689766
37 + 8689729 = 8689766
79 + 8689687 = 8689766
109 + 8689657 = 8689766
139 + 8689627 = 8689766
157 + 8689609 = 8689766
193 + 8689573 = 8689766
223 + 8689543 = 8689766

Showing the first eight; more decompositions exist.
