Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666988, here are decompositions:

61 + 8666927 = 8666988
97 + 8666891 = 8666988
107 + 8666881 = 8666988
139 + 8666849 = 8666988
149 + 8666839 = 8666988
179 + 8666809 = 8666988
181 + 8666807 = 8666988
191 + 8666797 = 8666988

Showing the first eight; more decompositions exist.
