Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978750, here are decompositions:

7 + 978743 = 978750
23 + 978727 = 978750
37 + 978713 = 978750
53 + 978697 = 978750
61 + 978689 = 978750
67 + 978683 = 978750
103 + 978647 = 978750
107 + 978643 = 978750

Showing the first eight; more decompositions exist.
