Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978916, here are decompositions:

53 + 978863 = 978916
167 + 978749 = 978916
173 + 978743 = 978916
227 + 978689 = 978916
233 + 978683 = 978916
269 + 978647 = 978916
317 + 978599 = 978916
347 + 978569 = 978916

Showing the first eight; more decompositions exist.
