Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971858, here are decompositions:

7 + 971851 = 971858
37 + 971821 = 971858
337 + 971521 = 971858
367 + 971491 = 971858
379 + 971479 = 971858
439 + 971419 = 971858
457 + 971401 = 971858
487 + 971371 = 971858

Showing the first eight; more decompositions exist.
