Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66864, here are decompositions:

11 + 66853 = 66864
13 + 66851 = 66864
23 + 66841 = 66864
43 + 66821 = 66864
67 + 66797 = 66864
73 + 66791 = 66864
101 + 66763 = 66864
113 + 66751 = 66864

Showing the first eight; more decompositions exist.
