Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971668, here are decompositions:

17 + 971651 = 971668
29 + 971639 = 971668
107 + 971561 = 971668
167 + 971501 = 971668
227 + 971441 = 971668
239 + 971429 = 971668
281 + 971387 = 971668
311 + 971357 = 971668

Showing the first eight; more decompositions exist.
