Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971646, here are decompositions:

7 + 971639 = 971646
83 + 971563 = 971646
97 + 971549 = 971646
163 + 971483 = 971646
167 + 971479 = 971646
173 + 971473 = 971646
227 + 971419 = 971646
257 + 971389 = 971646

Showing the first eight; more decompositions exist.
