Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018886, here are decompositions:

7 + 1018879 = 1018886
13 + 1018873 = 1018886
73 + 1018813 = 1018886
79 + 1018807 = 1018886
97 + 1018789 = 1018886
109 + 1018777 = 1018886
157 + 1018729 = 1018886
373 + 1018513 = 1018886

Showing the first eight; more decompositions exist.
