Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65816, here are decompositions:

7 + 65809 = 65816
97 + 65719 = 65816
103 + 65713 = 65816
109 + 65707 = 65816
139 + 65677 = 65816
199 + 65617 = 65816
229 + 65587 = 65816
277 + 65539 = 65816

Showing the first eight; more decompositions exist.
