Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000986, here are decompositions:

5 + 1000981 = 1000986
13 + 1000973 = 1000986
17 + 1000969 = 1000986
67 + 1000919 = 1000986
79 + 1000907 = 1000986
97 + 1000889 = 1000986
127 + 1000859 = 1000986
137 + 1000849 = 1000986

Showing the first eight; more decompositions exist.
