Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89988, here are decompositions:

5 + 89983 = 89988
11 + 89977 = 89988
29 + 89959 = 89988
71 + 89917 = 89988
79 + 89909 = 89988
89 + 89899 = 89988
97 + 89891 = 89988
139 + 89849 = 89988

Showing the first eight; more decompositions exist.
