Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018916, here are decompositions:

13 + 1018903 = 1018916
37 + 1018879 = 1018916
43 + 1018873 = 1018916
103 + 1018813 = 1018916
109 + 1018807 = 1018916
127 + 1018789 = 1018916
139 + 1018777 = 1018916
373 + 1018543 = 1018916

Showing the first eight; more decompositions exist.
