Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971840, here are decompositions:

7 + 971833 = 971840
19 + 971821 = 971840
73 + 971767 = 971840
127 + 971713 = 971840
157 + 971683 = 971840
271 + 971569 = 971840
277 + 971563 = 971840
349 + 971491 = 971840

Showing the first eight; more decompositions exist.
