Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971828, here are decompositions:

7 + 971821 = 971828
61 + 971767 = 971828
307 + 971521 = 971828
337 + 971491 = 971828
349 + 971479 = 971828
409 + 971419 = 971828
439 + 971389 = 971828
457 + 971371 = 971828

Showing the first eight; more decompositions exist.
