Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978554, here are decompositions:

13 + 978541 = 978554
43 + 978511 = 978554
97 + 978457 = 978554
127 + 978427 = 978554
151 + 978403 = 978554
211 + 978343 = 978554
271 + 978283 = 978554
277 + 978277 = 978554

Showing the first eight; more decompositions exist.
