Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65628, here are decompositions:

11 + 65617 = 65628
19 + 65609 = 65628
29 + 65599 = 65628
41 + 65587 = 65628
47 + 65581 = 65628
71 + 65557 = 65628
89 + 65539 = 65628
107 + 65521 = 65628

Showing the first eight; more decompositions exist.
