Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978948, here are decompositions:

17 + 978931 = 978948
31 + 978917 = 978948
41 + 978907 = 978948
97 + 978851 = 978948
109 + 978839 = 978948
127 + 978821 = 978948
149 + 978799 = 978948
151 + 978797 = 978948

Showing the first eight; more decompositions exist.
