Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978864, here are decompositions:

11 + 978853 = 978864
13 + 978851 = 978864
43 + 978821 = 978864
67 + 978797 = 978864
137 + 978727 = 978864
151 + 978713 = 978864
167 + 978697 = 978864
181 + 978683 = 978864

Showing the first eight; more decompositions exist.
