Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019850, here are decompositions:

11 + 1019839 = 1019850
23 + 1019827 = 1019850
31 + 1019819 = 1019850
67 + 1019783 = 1019850
79 + 1019771 = 1019850
103 + 1019747 = 1019850
109 + 1019741 = 1019850
127 + 1019723 = 1019850

Showing the first eight; more decompositions exist.
