Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971970, here are decompositions:

11 + 971959 = 971970
19 + 971951 = 971970
31 + 971939 = 971970
37 + 971933 = 971970
53 + 971917 = 971970
67 + 971903 = 971970
71 + 971899 = 971970
107 + 971863 = 971970

Showing the first eight; more decompositions exist.
