Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461988, here are decompositions:

5 + 461983 = 461988
11 + 461977 = 461988
17 + 461971 = 461988
31 + 461957 = 461988
67 + 461921 = 461988
71 + 461917 = 461988
97 + 461891 = 461988
101 + 461887 = 461988

Showing the first eight; more decompositions exist.
