Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42864, here are decompositions:

5 + 42859 = 42864
11 + 42853 = 42864
23 + 42841 = 42864
43 + 42821 = 42864
67 + 42797 = 42864
71 + 42793 = 42864
97 + 42767 = 42864
113 + 42751 = 42864

Showing the first eight; more decompositions exist.
