Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019808, here are decompositions:

7 + 1019801 = 1019808
37 + 1019771 = 1019808
61 + 1019747 = 1019808
67 + 1019741 = 1019808
79 + 1019729 = 1019808
107 + 1019701 = 1019808
109 + 1019699 = 1019808
151 + 1019657 = 1019808

Showing the first eight; more decompositions exist.
