Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667828, here are decompositions:

7 + 8667821 = 8667828
19 + 8667809 = 8667828
31 + 8667797 = 8667828
101 + 8667727 = 8667828
107 + 8667721 = 8667828
131 + 8667697 = 8667828
139 + 8667689 = 8667828
151 + 8667677 = 8667828

Showing the first eight; more decompositions exist.
