Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971980, here are decompositions:

3 + 971977 = 971980
29 + 971951 = 971980
41 + 971939 = 971980
47 + 971933 = 971980
59 + 971921 = 971980
197 + 971783 = 971980
227 + 971753 = 971980
257 + 971723 = 971980

Showing the first eight; more decompositions exist.
