Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689788, here are decompositions:

11 + 8689777 = 8689788
59 + 8689729 = 8689788
61 + 8689727 = 8689788
101 + 8689687 = 8689788
127 + 8689661 = 8689788
131 + 8689657 = 8689788
139 + 8689649 = 8689788
179 + 8689609 = 8689788

Showing the first eight; more decompositions exist.
