Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667824, here are decompositions:

3 + 8667821 = 8667824
31 + 8667793 = 8667824
97 + 8667727 = 8667824
103 + 8667721 = 8667824
127 + 8667697 = 8667824
163 + 8667661 = 8667824
211 + 8667613 = 8667824
223 + 8667601 = 8667824

Showing the first eight; more decompositions exist.
