Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049870, here are decompositions:

7 + 1049863 = 1049870
13 + 1049857 = 1049870
37 + 1049833 = 1049870
43 + 1049827 = 1049870
61 + 1049809 = 1049870
79 + 1049791 = 1049870
97 + 1049773 = 1049870
163 + 1049707 = 1049870

Showing the first eight; more decompositions exist.
