Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019884, here are decompositions:

11 + 1019873 = 1019884
23 + 1019861 = 1019884
83 + 1019801 = 1019884
101 + 1019783 = 1019884
113 + 1019771 = 1019884
137 + 1019747 = 1019884
167 + 1019717 = 1019884
191 + 1019693 = 1019884

Showing the first eight; more decompositions exist.
