Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12864, here are decompositions:

11 + 12853 = 12864
23 + 12841 = 12864
41 + 12823 = 12864
43 + 12821 = 12864
73 + 12791 = 12864
83 + 12781 = 12864
101 + 12763 = 12864
107 + 12757 = 12864

Showing the first eight; more decompositions exist.
