Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978756, here are decompositions:

7 + 978749 = 978756
13 + 978743 = 978756
29 + 978727 = 978756
43 + 978713 = 978756
59 + 978697 = 978756
67 + 978689 = 978756
73 + 978683 = 978756
109 + 978647 = 978756

Showing the first eight; more decompositions exist.
