Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688080, here are decompositions:

3 + 8688077 = 8688080
13 + 8688067 = 8688080
67 + 8688013 = 8688080
97 + 8687983 = 8688080
127 + 8687953 = 8688080
151 + 8687929 = 8688080
157 + 8687923 = 8688080
199 + 8687881 = 8688080

Showing the first eight; more decompositions exist.
