Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978434, here are decompositions:

7 + 978427 = 978434
31 + 978403 = 978434
97 + 978337 = 978434
151 + 978283 = 978434
157 + 978277 = 978434
211 + 978223 = 978434
277 + 978157 = 978434
283 + 978151 = 978434

Showing the first eight; more decompositions exist.
