Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667028, here are decompositions:

89 + 8666939 = 8667028
101 + 8666927 = 8667028
137 + 8666891 = 8667028
179 + 8666849 = 8667028
281 + 8666747 = 8667028
317 + 8666711 = 8667028
347 + 8666681 = 8667028
401 + 8666627 = 8667028

Showing the first eight; more decompositions exist.
