Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65886, here are decompositions:

5 + 65881 = 65886
19 + 65867 = 65886
43 + 65843 = 65886
47 + 65839 = 65886
59 + 65827 = 65886
97 + 65789 = 65886
109 + 65777 = 65886
157 + 65729 = 65886

Showing the first eight; more decompositions exist.
