Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485988, here are decompositions:

11 + 485977 = 485988
29 + 485959 = 485988
47 + 485941 = 485988
79 + 485909 = 485988
89 + 485899 = 485988
157 + 485831 = 485988
211 + 485777 = 485988
257 + 485731 = 485988

Showing the first eight; more decompositions exist.
