Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667864, here are decompositions:

17 + 8667847 = 8667864
43 + 8667821 = 8667864
67 + 8667797 = 8667864
71 + 8667793 = 8667864
131 + 8667733 = 8667864
137 + 8667727 = 8667864
157 + 8667707 = 8667864
167 + 8667697 = 8667864

Showing the first eight; more decompositions exist.
