Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689028, here are decompositions:

31 + 8688997 = 8689028
37 + 8688991 = 8689028
67 + 8688961 = 8689028
109 + 8688919 = 8689028
199 + 8688829 = 8689028
211 + 8688817 = 8689028
241 + 8688787 = 8689028
331 + 8688697 = 8689028

Showing the first eight; more decompositions exist.
