Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971988, here are decompositions:

7 + 971981 = 971988
11 + 971977 = 971988
29 + 971959 = 971988
37 + 971951 = 971988
67 + 971921 = 971988
71 + 971917 = 971988
89 + 971899 = 971988
131 + 971857 = 971988

Showing the first eight; more decompositions exist.
