Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667904, here are decompositions:

5 + 8667899 = 8667904
41 + 8667863 = 8667904
83 + 8667821 = 8667904
107 + 8667797 = 8667904
197 + 8667707 = 8667904
227 + 8667677 = 8667904
251 + 8667653 = 8667904
263 + 8667641 = 8667904

Showing the first eight; more decompositions exist.
