Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978768, here are decompositions:

19 + 978749 = 978768
41 + 978727 = 978768
71 + 978697 = 978768
79 + 978689 = 978768
149 + 978619 = 978768
151 + 978617 = 978768
157 + 978611 = 978768
199 + 978569 = 978768

Showing the first eight; more decompositions exist.
