Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978456, here are decompositions:

7 + 978449 = 978456
29 + 978427 = 978456
43 + 978413 = 978456
53 + 978403 = 978456
67 + 978389 = 978456
97 + 978359 = 978456
107 + 978349 = 978456
109 + 978347 = 978456

Showing the first eight; more decompositions exist.
