Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971978, here are decompositions:

19 + 971959 = 971978
61 + 971917 = 971978
79 + 971899 = 971978
127 + 971851 = 971978
157 + 971821 = 971978
211 + 971767 = 971978
409 + 971569 = 971978
457 + 971521 = 971978

Showing the first eight; more decompositions exist.
