Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979986, here are decompositions:

17 + 979969 = 979986
37 + 979949 = 979986
67 + 979919 = 979986
79 + 979907 = 979986
97 + 979889 = 979986
103 + 979883 = 979986
113 + 979873 = 979986
167 + 979819 = 979986

Showing the first eight; more decompositions exist.
