Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65690, here are decompositions:

3 + 65687 = 65690
13 + 65677 = 65690
43 + 65647 = 65690
61 + 65629 = 65690
73 + 65617 = 65690
103 + 65587 = 65690
109 + 65581 = 65690
127 + 65563 = 65690

Showing the first eight; more decompositions exist.
