Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015824, here are decompositions:

11 + 1015813 = 1015824
71 + 1015753 = 1015824
97 + 1015727 = 1015824
101 + 1015723 = 1015824
127 + 1015697 = 1015824
163 + 1015661 = 1015824
197 + 1015627 = 1015824
223 + 1015601 = 1015824

Showing the first eight; more decompositions exist.
