Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017870, here are decompositions:

11 + 1017859 = 1017870
13 + 1017857 = 1017870
19 + 1017851 = 1017870
23 + 1017847 = 1017870
43 + 1017827 = 1017870
53 + 1017817 = 1017870
71 + 1017799 = 1017870
83 + 1017787 = 1017870

Showing the first eight; more decompositions exist.
