Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65770, here are decompositions:

41 + 65729 = 65770
53 + 65717 = 65770
71 + 65699 = 65770
83 + 65687 = 65770
113 + 65657 = 65770
137 + 65633 = 65770
191 + 65579 = 65770
227 + 65543 = 65770

Showing the first eight; more decompositions exist.
