Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978918, here are decompositions:

11 + 978907 = 978918
47 + 978871 = 978918
67 + 978851 = 978918
79 + 978839 = 978918
97 + 978821 = 978918
191 + 978727 = 978918
229 + 978689 = 978918
271 + 978647 = 978918

Showing the first eight; more decompositions exist.
