Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018824, here are decompositions:

7 + 1018817 = 1018824
11 + 1018813 = 1018824
13 + 1018811 = 1018824
17 + 1018807 = 1018824
47 + 1018777 = 1018824
61 + 1018763 = 1018824
113 + 1018711 = 1018824
127 + 1018697 = 1018824

Showing the first eight; more decompositions exist.
