Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971928, here are decompositions:

7 + 971921 = 971928
11 + 971917 = 971928
29 + 971899 = 971928
71 + 971857 = 971928
107 + 971821 = 971928
229 + 971699 = 971928
277 + 971651 = 971928
337 + 971591 = 971928

Showing the first eight; more decompositions exist.
