Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971686, here are decompositions:

3 + 971683 = 971686
47 + 971639 = 971686
137 + 971549 = 971686
173 + 971513 = 971686
257 + 971429 = 971686
347 + 971339 = 971686
449 + 971237 = 971686
479 + 971207 = 971686

Showing the first eight; more decompositions exist.
