Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971722, here are decompositions:

23 + 971699 = 971722
29 + 971693 = 971722
71 + 971651 = 971722
83 + 971639 = 971722
131 + 971591 = 971722
173 + 971549 = 971722
239 + 971483 = 971722
281 + 971441 = 971722

Showing the first eight; more decompositions exist.
