Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971172, here are decompositions:

19 + 971153 = 971172
23 + 971149 = 971172
29 + 971143 = 971172
31 + 971141 = 971172
61 + 971111 = 971172
73 + 971099 = 971172
79 + 971093 = 971172
109 + 971063 = 971172

Showing the first eight; more decompositions exist.
