Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996990, here are decompositions:

11 + 996979 = 996990
17 + 996973 = 996990
23 + 996967 = 996990
37 + 996953 = 996990
103 + 996887 = 996990
107 + 996883 = 996990
109 + 996881 = 996990
131 + 996859 = 996990

Showing the first eight; more decompositions exist.
