Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966978, here are decompositions:

7 + 966971 = 966978
17 + 966961 = 966978
41 + 966937 = 966978
59 + 966919 = 966978
71 + 966907 = 966978
107 + 966871 = 966978
109 + 966869 = 966978
197 + 966781 = 966978

Showing the first eight; more decompositions exist.
