Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978946, here are decompositions:

29 + 978917 = 978946
83 + 978863 = 978946
107 + 978839 = 978946
149 + 978797 = 978946
173 + 978773 = 978946
197 + 978749 = 978946
233 + 978713 = 978946
257 + 978689 = 978946

Showing the first eight; more decompositions exist.
