Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978494, here are decompositions:

3 + 978491 = 978494
31 + 978463 = 978494
37 + 978457 = 978494
67 + 978427 = 978494
151 + 978343 = 978494
157 + 978337 = 978494
211 + 978283 = 978494
271 + 978223 = 978494

Showing the first eight; more decompositions exist.
