Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020888, here are decompositions:

7 + 1020881 = 1020888
41 + 1020847 = 1020888
47 + 1020841 = 1020888
61 + 1020827 = 1020888
67 + 1020821 = 1020888
109 + 1020779 = 1020888
131 + 1020757 = 1020888
137 + 1020751 = 1020888

Showing the first eight; more decompositions exist.
