Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688012, here are decompositions:

19 + 8687993 = 8688012
29 + 8687983 = 8688012
31 + 8687981 = 8688012
59 + 8687953 = 8688012
83 + 8687929 = 8688012
89 + 8687923 = 8688012
101 + 8687911 = 8688012
131 + 8687881 = 8688012

Showing the first eight; more decompositions exist.
