Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56988, here are decompositions:

5 + 56983 = 56988
31 + 56957 = 56988
37 + 56951 = 56988
47 + 56941 = 56988
59 + 56929 = 56988
67 + 56921 = 56988
79 + 56909 = 56988
97 + 56891 = 56988

Showing the first eight; more decompositions exist.
