Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979740, here are decompositions:

23 + 979717 = 979740
31 + 979709 = 979740
89 + 979651 = 979740
173 + 979567 = 979740
191 + 979549 = 979740
197 + 979543 = 979740
199 + 979541 = 979740
211 + 979529 = 979740

Showing the first eight; more decompositions exist.
