Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971918, here are decompositions:

19 + 971899 = 971918
61 + 971857 = 971918
67 + 971851 = 971918
97 + 971821 = 971918
151 + 971767 = 971918
349 + 971569 = 971918
397 + 971521 = 971918
439 + 971479 = 971918

Showing the first eight; more decompositions exist.
