Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048920, here are decompositions:

11 + 1048909 = 1048920
23 + 1048897 = 1048920
29 + 1048891 = 1048920
31 + 1048889 = 1048920
43 + 1048877 = 1048920
53 + 1048867 = 1048920
73 + 1048847 = 1048920
83 + 1048837 = 1048920

Showing the first eight; more decompositions exist.
