Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971690, here are decompositions:

7 + 971683 = 971690
37 + 971653 = 971690
127 + 971563 = 971690
199 + 971491 = 971690
211 + 971479 = 971690
271 + 971419 = 971690
337 + 971353 = 971690
409 + 971281 = 971690

Showing the first eight; more decompositions exist.
