Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65920, here are decompositions:

53 + 65867 = 65920
83 + 65837 = 65920
89 + 65831 = 65920
131 + 65789 = 65920
191 + 65729 = 65920
233 + 65687 = 65920
263 + 65657 = 65920
269 + 65651 = 65920

Showing the first eight; more decompositions exist.
