Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697988, here are decompositions:

11 + 8697977 = 8697988
17 + 8697971 = 8697988
41 + 8697947 = 8697988
137 + 8697851 = 8697988
179 + 8697809 = 8697988
191 + 8697797 = 8697988
197 + 8697791 = 8697988
281 + 8697707 = 8697988

Showing the first eight; more decompositions exist.
