Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019856, here are decompositions:

7 + 1019849 = 1019856
17 + 1019839 = 1019856
29 + 1019827 = 1019856
37 + 1019819 = 1019856
73 + 1019783 = 1019856
109 + 1019747 = 1019856
127 + 1019729 = 1019856
139 + 1019717 = 1019856

Showing the first eight; more decompositions exist.
