Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688018, here are decompositions:

5 + 8688013 = 8688018
7 + 8688011 = 8688018
37 + 8687981 = 8688018
89 + 8687929 = 8688018
107 + 8687911 = 8688018
127 + 8687891 = 8688018
137 + 8687881 = 8688018
139 + 8687879 = 8688018

Showing the first eight; more decompositions exist.
