Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979638, here are decompositions:

71 + 979567 = 979638
89 + 979549 = 979638
97 + 979541 = 979638
109 + 979529 = 979638
157 + 979481 = 979638
167 + 979471 = 979638
181 + 979457 = 979638
199 + 979439 = 979638

Showing the first eight; more decompositions exist.
