Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979644, here are decompositions:

101 + 979543 = 979644
103 + 979541 = 979644
163 + 979481 = 979644
173 + 979471 = 979644
241 + 979403 = 979644
271 + 979373 = 979644
283 + 979361 = 979644
307 + 979337 = 979644

Showing the first eight; more decompositions exist.
