Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971638, here are decompositions:

47 + 971591 = 971638
89 + 971549 = 971638
137 + 971501 = 971638
197 + 971441 = 971638
251 + 971387 = 971638
257 + 971381 = 971638
281 + 971357 = 971638
347 + 971291 = 971638

Showing the first eight; more decompositions exist.
