Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689986, here are decompositions:

5 + 8689981 = 8689986
7 + 8689979 = 8689986
17 + 8689969 = 8689986
29 + 8689957 = 8689986
37 + 8689949 = 8689986
43 + 8689943 = 8689986
163 + 8689823 = 8689986
233 + 8689753 = 8689986

Showing the first eight; more decompositions exist.
