Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65988, here are decompositions:

5 + 65983 = 65988
7 + 65981 = 65988
31 + 65957 = 65988
37 + 65951 = 65988
59 + 65929 = 65988
61 + 65927 = 65988
67 + 65921 = 65988
89 + 65899 = 65988

Showing the first eight; more decompositions exist.
