Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002864, here are decompositions:

7 + 1002857 = 1002864
11 + 1002853 = 1002864
13 + 1002851 = 1002864
43 + 1002821 = 1002864
47 + 1002817 = 1002864
67 + 1002797 = 1002864
97 + 1002767 = 1002864
113 + 1002751 = 1002864

Showing the first eight; more decompositions exist.
