Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689836, here are decompositions:

13 + 8689823 = 8689836
19 + 8689817 = 8689836
37 + 8689799 = 8689836
59 + 8689777 = 8689836
83 + 8689753 = 8689836
107 + 8689729 = 8689836
109 + 8689727 = 8689836
149 + 8689687 = 8689836

Showing the first eight; more decompositions exist.
