Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564988, here are decompositions:

5 + 564983 = 564988
29 + 564959 = 564988
71 + 564917 = 564988
89 + 564899 = 564988
107 + 564881 = 564988
191 + 564797 = 564988
227 + 564761 = 564988
317 + 564671 = 564988

Showing the first eight; more decompositions exist.
