Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978656, here are decompositions:

13 + 978643 = 978656
37 + 978619 = 978656
193 + 978463 = 978656
199 + 978457 = 978656
229 + 978427 = 978656
307 + 978349 = 978656
313 + 978343 = 978656
373 + 978283 = 978656

Showing the first eight; more decompositions exist.
