Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978474, here are decompositions:

11 + 978463 = 978474
17 + 978457 = 978474
47 + 978427 = 978474
61 + 978413 = 978474
71 + 978403 = 978474
127 + 978347 = 978474
131 + 978343 = 978474
137 + 978337 = 978474

Showing the first eight; more decompositions exist.
