Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971688, here are decompositions:

5 + 971683 = 971688
37 + 971651 = 971688
97 + 971591 = 971688
127 + 971561 = 971688
139 + 971549 = 971688
167 + 971521 = 971688
197 + 971491 = 971688
269 + 971419 = 971688

Showing the first eight; more decompositions exist.
