Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978396, here are decompositions:

7 + 978389 = 978396
37 + 978359 = 978396
47 + 978349 = 978396
53 + 978343 = 978396
59 + 978337 = 978396
73 + 978323 = 978396
109 + 978287 = 978396
113 + 978283 = 978396

Showing the first eight; more decompositions exist.
