Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667970, here are decompositions:

41 + 8667929 = 8667970
71 + 8667899 = 8667970
107 + 8667863 = 8667970
149 + 8667821 = 8667970
173 + 8667797 = 8667970
263 + 8667707 = 8667970
281 + 8667689 = 8667970
293 + 8667677 = 8667970

Showing the first eight; more decompositions exist.
