Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951978, here are decompositions:

11 + 951967 = 951978
19 + 951959 = 951978
37 + 951941 = 951978
67 + 951911 = 951978
127 + 951851 = 951978
149 + 951829 = 951978
191 + 951787 = 951978
197 + 951781 = 951978

Showing the first eight; more decompositions exist.
