Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65982, here are decompositions:

19 + 65963 = 65982
31 + 65951 = 65982
53 + 65929 = 65982
61 + 65921 = 65982
83 + 65899 = 65982
101 + 65881 = 65982
131 + 65851 = 65982
139 + 65843 = 65982

Showing the first eight; more decompositions exist.
