Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978944, here are decompositions:

13 + 978931 = 978944
37 + 978907 = 978944
61 + 978883 = 978944
73 + 978871 = 978944
433 + 978511 = 978944
487 + 978457 = 978944
541 + 978403 = 978944
601 + 978343 = 978944

Showing the first eight; more decompositions exist.
