Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689860, here are decompositions:

7 + 8689853 = 8689860
17 + 8689843 = 8689860
19 + 8689841 = 8689860
37 + 8689823 = 8689860
43 + 8689817 = 8689860
61 + 8689799 = 8689860
83 + 8689777 = 8689860
107 + 8689753 = 8689860

Showing the first eight; more decompositions exist.
