Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019806, here are decompositions:

5 + 1019801 = 1019806
23 + 1019783 = 1019806
59 + 1019747 = 1019806
83 + 1019723 = 1019806
89 + 1019717 = 1019806
107 + 1019699 = 1019806
113 + 1019693 = 1019806
149 + 1019657 = 1019806

Showing the first eight; more decompositions exist.
