Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019838, here are decompositions:

11 + 1019827 = 1019838
19 + 1019819 = 1019838
37 + 1019801 = 1019838
67 + 1019771 = 1019838
97 + 1019741 = 1019838
107 + 1019731 = 1019838
109 + 1019729 = 1019838
137 + 1019701 = 1019838

Showing the first eight; more decompositions exist.
