Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996978, here are decompositions:

5 + 996973 = 996978
11 + 996967 = 996978
79 + 996899 = 996978
97 + 996881 = 996978
107 + 996871 = 996978
131 + 996847 = 996978
137 + 996841 = 996978
167 + 996811 = 996978

Showing the first eight; more decompositions exist.
