Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978900, here are decompositions:

17 + 978883 = 978900
29 + 978871 = 978900
37 + 978863 = 978900
47 + 978853 = 978900
61 + 978839 = 978900
79 + 978821 = 978900
101 + 978799 = 978900
103 + 978797 = 978900

Showing the first eight; more decompositions exist.
