Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996980, here are decompositions:

7 + 996973 = 996980
13 + 996967 = 996980
97 + 996883 = 996980
109 + 996871 = 996980
139 + 996841 = 996980
199 + 996781 = 996980
241 + 996739 = 996980
277 + 996703 = 996980

Showing the first eight; more decompositions exist.
