Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978726, here are decompositions:

13 + 978713 = 978726
29 + 978697 = 978726
37 + 978689 = 978726
43 + 978683 = 978726
79 + 978647 = 978726
83 + 978643 = 978726
107 + 978619 = 978726
109 + 978617 = 978726

Showing the first eight; more decompositions exist.
