Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978718, here are decompositions:

5 + 978713 = 978718
29 + 978689 = 978718
71 + 978647 = 978718
101 + 978617 = 978718
107 + 978611 = 978718
149 + 978569 = 978718
197 + 978521 = 978718
227 + 978491 = 978718

Showing the first eight; more decompositions exist.
