Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019866, here are decompositions:

5 + 1019861 = 1019866
17 + 1019849 = 1019866
47 + 1019819 = 1019866
83 + 1019783 = 1019866
137 + 1019729 = 1019866
149 + 1019717 = 1019866
167 + 1019699 = 1019866
173 + 1019693 = 1019866

Showing the first eight; more decompositions exist.
