Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020870, here are decompositions:

17 + 1020853 = 1020870
23 + 1020847 = 1020870
29 + 1020841 = 1020870
31 + 1020839 = 1020870
43 + 1020827 = 1020870
47 + 1020823 = 1020870
73 + 1020797 = 1020870
113 + 1020757 = 1020870

Showing the first eight; more decompositions exist.
