Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971838, here are decompositions:

5 + 971833 = 971838
17 + 971821 = 971838
71 + 971767 = 971838
79 + 971759 = 971838
139 + 971699 = 971838
199 + 971639 = 971838
269 + 971569 = 971838
277 + 971561 = 971838

Showing the first eight; more decompositions exist.
