Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65806, here are decompositions:

17 + 65789 = 65806
29 + 65777 = 65806
89 + 65717 = 65806
107 + 65699 = 65806
149 + 65657 = 65806
173 + 65633 = 65806
197 + 65609 = 65806
227 + 65579 = 65806

Showing the first eight; more decompositions exist.
