Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996986, here are decompositions:

7 + 996979 = 996986
13 + 996973 = 996986
19 + 996967 = 996986
103 + 996883 = 996986
127 + 996859 = 996986
139 + 996847 = 996986
223 + 996763 = 996986
283 + 996703 = 996986

Showing the first eight; more decompositions exist.
