Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971128, here are decompositions:

17 + 971111 = 971128
29 + 971099 = 971128
89 + 971039 = 971128
101 + 971027 = 971128
107 + 971021 = 971128
131 + 970997 = 971128
167 + 970961 = 971128
251 + 970877 = 971128

Showing the first eight; more decompositions exist.
