Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705988, here are decompositions:

19 + 8705969 = 8705988
29 + 8705959 = 8705988
47 + 8705941 = 8705988
107 + 8705881 = 8705988
127 + 8705861 = 8705988
157 + 8705831 = 8705988
197 + 8705791 = 8705988
211 + 8705777 = 8705988

Showing the first eight; more decompositions exist.
