Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65916, here are decompositions:

17 + 65899 = 65916
73 + 65843 = 65916
79 + 65837 = 65916
89 + 65827 = 65916
107 + 65809 = 65916
127 + 65789 = 65916
139 + 65777 = 65916
197 + 65719 = 65916

Showing the first eight; more decompositions exist.
