Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971998, here are decompositions:

17 + 971981 = 971998
47 + 971951 = 971998
59 + 971939 = 971998
239 + 971759 = 971998
347 + 971651 = 971998
359 + 971639 = 971998
449 + 971549 = 971998
557 + 971441 = 971998

Showing the first eight; more decompositions exist.
