Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978888, here are decompositions:

5 + 978883 = 978888
17 + 978871 = 978888
37 + 978851 = 978888
67 + 978821 = 978888
89 + 978799 = 978888
139 + 978749 = 978888
191 + 978697 = 978888
199 + 978689 = 978888

Showing the first eight; more decompositions exist.
