Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978720, here are decompositions:

7 + 978713 = 978720
23 + 978697 = 978720
31 + 978689 = 978720
37 + 978683 = 978720
73 + 978647 = 978720
101 + 978619 = 978720
103 + 978617 = 978720
109 + 978611 = 978720

Showing the first eight; more decompositions exist.
