Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002870, here are decompositions:

7 + 1002863 = 1002870
13 + 1002857 = 1002870
17 + 1002853 = 1002870
19 + 1002851 = 1002870
53 + 1002817 = 1002870
61 + 1002809 = 1002870
73 + 1002797 = 1002870
83 + 1002787 = 1002870

Showing the first eight; more decompositions exist.
