Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666998, here are decompositions:

5 + 8666993 = 8666998
59 + 8666939 = 8666998
71 + 8666927 = 8666998
107 + 8666891 = 8666998
149 + 8666849 = 8666998
191 + 8666807 = 8666998
251 + 8666747 = 8666998
317 + 8666681 = 8666998

Showing the first eight; more decompositions exist.
