Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978894, here are decompositions:

11 + 978883 = 978894
23 + 978871 = 978894
31 + 978863 = 978894
41 + 978853 = 978894
43 + 978851 = 978894
73 + 978821 = 978894
97 + 978797 = 978894
151 + 978743 = 978894

Showing the first eight; more decompositions exist.
