Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971156, here are decompositions:

3 + 971153 = 971156
7 + 971149 = 971156
13 + 971143 = 971156
79 + 971077 = 971156
103 + 971053 = 971156
127 + 971029 = 971156
157 + 970999 = 971156
229 + 970927 = 971156

Showing the first eight; more decompositions exist.
