Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019886, here are decompositions:

13 + 1019873 = 1019886
29 + 1019857 = 1019886
37 + 1019849 = 1019886
47 + 1019839 = 1019886
59 + 1019827 = 1019886
67 + 1019819 = 1019886
103 + 1019783 = 1019886
139 + 1019747 = 1019886

Showing the first eight; more decompositions exist.
