Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65712, here are decompositions:

5 + 65707 = 65712
11 + 65701 = 65712
13 + 65699 = 65712
61 + 65651 = 65712
79 + 65633 = 65712
83 + 65629 = 65712
103 + 65609 = 65712
113 + 65599 = 65712

Showing the first eight; more decompositions exist.
