Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019916, here are decompositions:

13 + 1019903 = 1019916
17 + 1019899 = 1019916
43 + 1019873 = 1019916
59 + 1019857 = 1019916
67 + 1019849 = 1019916
89 + 1019827 = 1019916
97 + 1019819 = 1019916
193 + 1019723 = 1019916

Showing the first eight; more decompositions exist.
