Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971142, here are decompositions:

31 + 971111 = 971142
43 + 971099 = 971142
79 + 971063 = 971142
89 + 971053 = 971142
103 + 971039 = 971142
113 + 971029 = 971142
173 + 970969 = 971142
181 + 970961 = 971142

Showing the first eight; more decompositions exist.
