Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978440, here are decompositions:

13 + 978427 = 978440
37 + 978403 = 978440
97 + 978343 = 978440
103 + 978337 = 978440
157 + 978283 = 978440
163 + 978277 = 978440
223 + 978217 = 978440
283 + 978157 = 978440

Showing the first eight; more decompositions exist.
